Question

Help!! Please explain how you go it too please!!

Answer 1

6 + 2x = x - 6
2x = x - 6 - 6
2x = x - 12
2x - x = -12
x = -12

SIMPLER WAY
6 + 2x = x - 6
Subtract 6 from both sides;
2x = x - 12
2x - x = -12
x = -12

CHECK

6 + - 24 = -12 - 6
-18 = 18!

Therefore if you see one of my workouts it has 2x - x = 12 so the one at the very right (2x - x = 12) is the answer :)

Answer 2

`6+2x=x-6`

`2x-x=-6-6`

`x=-12`

The anwers is - the last equation, because having solved it, it is the same value :

`2x=x-12`

`2x-x=-12`
x=-12

I hope I was of help ;)
