Best ResponseYou've already chosen the best response.02(3x+7) multiply the 2 to each term inside the parenthesis 2*3x + 2*7 6x + 14 do that for each one

Best ResponseYou've already chosen the best response.0so the next one would be 4x3+4x2 = 12x+8

Best ResponseYou've already chosen the best response.0the next is 6x5+6x9 = 30x+54

Best ResponseYou've already chosen the best response.0good now add terms that have the same variable ex: 2x4x = 2x you cant add constants with x's

Best ResponseYou've already chosen the best response.0i just noticed i messed up on the first one it should be 6x14

Best ResponseYou've already chosen the best response.0I saw its okay. I wrote it down as subtraction

Best ResponseYou've already chosen the best response.0so my problem now shows 6x14+12x+8=30x+54+3 right

Best ResponseYou've already chosen the best response.0If I put the x's together

Best ResponseYou've already chosen the best response.0almost dont forget theres an "=" sign separating them so add 6x+12x = 18x but keep 30x on other side for now

Best ResponseYou've already chosen the best response.0okay so then it becomes......6x+12x=18x+30x+54

Best ResponseYou've already chosen the best response.0ugh....no its.....18x14+12=30x+54+3

dumbcow

Best ResponseYou've already chosen the best response.0good now add the constants together on both sides

Best ResponseYou've already chosen the best response.0oops...my problems got mixed up some how.....let me back up. It should be 18x14+8=30x+54+3

anonymous

Best ResponseYou've already chosen the best response.0okay so now I get......18x6=30x+57

Best ResponseYou've already chosen the best response.0now we want to combine terms from the other side of the equal sign lets add 6 to both sides this works because 6+6=0 on left side

anonymous

Best ResponseYou've already chosen the best response.0so left side is just now 18x=30x+57+6 which is 8x=30x+63

Best ResponseYou've already chosen the best response.0very good now to get all the x's on the left we should do what?

anonymous

Best ResponseYou've already chosen the best response.0would I subtract them since the left side was subtracting??

dumbcow

Best ResponseYou've already chosen the best response.0yes, the goal is to cancel the x's on the right

Best ResponseYou've already chosen the best response.018x=63 thats what I am left with right?

dumbcow

Best ResponseYou've already chosen the best response.0remember before we added 6 to both sides same here whatever you do to one side you do to the other so we have to subtract 30x on the left too

dumbcow

Best ResponseYou've already chosen the best response.0watch out for your signs (1830=12) 2/2 = 1 4/4 =1 so if we divide a num by itself we always get 1 and the goal is to have 1x on the left side but right now we have 12 so have to divide by 12 on both sides

anonymous

Best ResponseYou've already chosen the best response.0so if we divide 63 by 12 it comes to 5.25. so x=5.25

dumbcow

Best ResponseYou've already chosen the best response.0almost watch those signs its negative but yes the number is correct :)
