x = 0.6x + 384 -.6x -.6x ----------------- .4x = 384 what should x be?
almost .. you forgot a 0
384/.4 = 960
helping out on some others
dunno, i havent seen the others ... they might scare me
Solve for : x + 20 / 2 = 3x
use your grouping symbols correctly ... im assuming (x+20) is on top?
what is your thoughts then, how would you try to work this?
Ill show you
Wait... Ima do this on notepad
I know that you first have to single x out onto 1 side of the line, but what confuses me is the division thing. I know with division you have to find a Least common denominator, but since there is only one division problem here, Im clueless as how to go on.
whatever we do to one side, we do to the other .... A/2 = B ... in order to UNDO division, we multiply 2A/2 = 2B A = 2B
i would start out by multiplying both sides by that denominator
So multiply both sides by 2 and get rid of the 2 on the first side?
yep x+20 = 2(3x) x+20 = 6x ... now what are your thoughts?
There is an x on both sides, so you have to get them onto one side. Which side do I choose?
either side works ... personally is move the leftside over but it doesnt matter
20 = 5x?
subtraction UNDOES addition soo x+20 = 6x -x -x ----------- 20 = 5x yes, now what is our x value?
if we had options, we could have also tried them to see what worked
I have one more. You wanna help pal?
one more, fine
Here I will snip and send pic
i few things wrong with this ... some would contend that this is cheating on an exam; but the more important thing is that you have posted personal information that is contained in the picture.
anyways, you know how to distribute?
Its no exam, XD Its a module test.
3x + 3 = -2x - 2 + 6
mrs collins, santiago, seminole county ... none of that needs to be posted publically is all. its a safety issue for minors
-2(-1) is not -2
dont forget your negative rules :)
Seriously? I could give out my homestate and city, there would still be about 1000+ collins and Santiagos to pick fro. That and you dont even know my address.
3x + 3 = -2x + 2 + 6 now what?
3x + 3 = -2x + 2 + 6 3x + 3 = -2x + 8 3x = -2x + 5?
so far so good, now add 2x to get rid of the -2x and we should be good
3(x + 1) = −2(x − 1) + 6. 3x + 3 = -2x + 2 + 6 3x + 3 = -2x + 8 3x = -2x + 5? +2x +2x 5x = 5 x = 1 Thanks pal! :D
good luck :)
