3x + 7= x  1
3x=x(62x)
12x5=4x+2
2x+3=2x+5
I cant remember the steps to evaluate.

3x + 7= x  1
4x = 1 7
4x = 8
x = 2
____________________________
3x=x(62x)
3x = x  6 + 2x
6x = 6
x = 1

You try the other two problems. I'll be glad to check your answers. 
2x+3=2x+5
I think the answer is 8
______________________________
12x5=4x+2
2x=8?
X=4?
I doubt I got this right
