Best ResponseYou've already chosen the best response.0but d is the same so how would d=c?

Best ResponseYou've already chosen the best response.0hmmm, ok, like this: (x+y)(u+v)=xu+xv+yu+yv apply this into your equation x=d, y=7, u=d, v=4/3

Best ResponseYou've already chosen the best response.0no way ttt, d can't equal 7, that makes the equality false!

Best ResponseYou've already chosen the best response.0im solving it it will =0 like this, (x4)(X+2)=0 so x4=0 and x+2=0

Best ResponseYou've already chosen the best response.0howdoes x=4 when it is x4=0

anonymous

Best ResponseYou've already chosen the best response.0if you add 4 to both sides of the equation x  4 = 0 you get x = 4

Best ResponseYou've already chosen the best response.0what do i do from there i add 7 and 4/3 to each side?

anonymous

Best ResponseYou've already chosen the best response.0no, you add 7 and subtract 4/3

Best ResponseYou've already chosen the best response.0what would my answer be if they both =0 would it be d=0?

anonymous

Best ResponseYou've already chosen the best response.0they both don't equal 0, only one at a time

Best ResponseYou've already chosen the best response.0wait so i do 4/3d or 0

anonymous

Best ResponseYou've already chosen the best response.0what would i do 7+d or 7+0???

anonymous

Best ResponseYou've already chosen the best response.0what? d is two distinct answers d ={7, 4/3}

anonymous

Best ResponseYou've already chosen the best response.0but if d7=0 and d+4/3=0 what would i do then

anonymous

Best ResponseYou've already chosen the best response.0that means that d has two solutions 7 and 4/3

Best ResponseYou've already chosen the best response.0(d7)(d+4/3)=0 d7=0, d=7 because 77=0 d+4/3=0, d=4/3 because 4/3+4/3=0 which part don't you understand? dont make it too complicated.

anonymous

Best ResponseYou've already chosen the best response.0why would it be 7+7? d=7, so you change letter d in the equation into number 7. you didn't touch the minus sign at all so how can it become +

anonymous

Best ResponseYou've already chosen the best response.0because d7=0 add 7 to each side right?

anonymous

Best ResponseYou've already chosen the best response.0ohhh ok i get it if it = 0 than it would be corect right?

anonymous

Best ResponseYou've already chosen the best response.0that's what people always do, I dont. why add more stuff? think this way. you have 7 on the right, now change it to the left. everytime you change side of anything, you change the sign. that number 7 on the left, you have  before it, so it's 7. now you move 7 to the left, you change the sign. So 7 on the right become +7 on the left. done

Best ResponseYou've already chosen the best response.0now try this, a6+12=2, lets see if you get it right.

anonymous

Best ResponseYou've already chosen the best response.0idk do i add 6 to each side?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0no no, dont add anything, move it to the other side. what you have on the left? you have (6) and (+12) right? so change the side. remember, CHANGE SIDE, CHANGE SIGN. (6) from left to right become +6, +12 left to right be come 12. can u do the rest now?

anonymous

Best ResponseYou've already chosen the best response.0that 12 there, why is it still on the left. It should be changed to the right to become 12. a=2+612 like that try another one x+57=1 remember, if you change its side, also change its sign, if not, nothing happen

Best ResponseYou've already chosen the best response.0absolutely right. how about 59=7x

anonymous

Best ResponseYou've already chosen the best response.0should be x, because x wasn't changed side, right? 7+59=x u understand this part?

anonymous

Best ResponseYou've already chosen the best response.0so I think you get it now. back to the problem, you have d7=0 or d+4/3=0 just do the same, change side, change sign.

anonymous

Best ResponseYou've already chosen the best response.0??? no, keep d in one side, push everything else to the other side, because you're finding d here. do again?

anonymous

Best ResponseYou've already chosen the best response.0ohh ok because im ffinding d it would be 0+7=d?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0that's alright, but you just begin with this method, so try follow the rule d7=0 7=d (see, change side, change sign) d=7 (again, change side, change sign)

anonymous

Best ResponseYou've already chosen the best response.0if you move anything from left to right or right to left, change the sign that go with it. eg. 7 on the left becomes 7 on the right or x on the right, become x on the left

Best ResponseYou've already chosen the best response.0my aint used to make me do this stuff for the whole day. she's a teacher

anonymous

Best ResponseYou've already chosen the best response.0that's ok but you shouldn't do it that way because it could easily get wrong. you have d+4/3=0 what you wanna find should be on the left, so d stay. 4/3 on the left, moved to the right, becomes 4/3 so d=4/3

anonymous

Best ResponseYou've already chosen the best response.0i want to do this stuff all day just dont have the stuff to do it so my friend aarman who is great on this site showed me it so i come on here

anonymous

Best ResponseYou've already chosen the best response.0lol, 0 is nothing, just thought it away. anything add up with 0 become itself. right, can you solve this: d1/4+5=0 remember, d stay, everything else go.

anonymous

Best ResponseYou've already chosen the best response.0you forgot to change sign of 1/4. can you see that mistake?

anonymous

Best ResponseYou've already chosen the best response.0on the left, it's 1/4, so on the right, what should it be?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0that's right. I'm gonna go to sleep now, but try this last one first. 4d+53+12=17d+2/3 remember bring all the d to the left and all the number to the right. and do slowly step by step, no rush

anonymous

Best ResponseYou've already chosen the best response.0not really, you know left and right right? (left)=(right) look at the term d first, we have 4d on the left, so keep it, 7d on the right, bring it to the left, change the sign, become 7d. so on the left you have 4d+7d on the right, there's 1 and 2/3, keep them. there're +53+12 on the left, bring them to the right, change sign, become 5+312 so the right: 1+2/35+312 then equation is 4d+7d=1+2/35+312 compare these two: 4d+53+12=17d+2/3 (origin) 4d+7d=1+2/35+312 (after changing) I'll put some brackets for clarity (4d) + 5 3 +12 = 1 (7d) +2/3 (origin) (4d) +(7d) = 1 +2/3 5 +3 12 (after changing)
