Question

2x+9=5x-12
can someone please help me??

Answer 1

This is English...lol

Answer 2

Anyway... what you do is take away 5x on the right

Answer 3

so 5x-5x cancels each other out..so your equation should look like, 2x-5x+9=-12 (because what you do on one side, you do to the other)

Answer 4

you subtract 2x-5x, you get -3x....so -3x+9=-12

Answer 5

You isolate -3x by getting rid of 9 by subtracting it, so 9-9=0.....
then you do the same on the other side...so -3x=-21

Answer 6

divide by -3 on both sides and x=7
