SOLUTION: How do I solve this equation, 4x - 7 = 2x - 7 I added 7 to both sides, so it looks like this to isolate 4x on the left. 4x -7 + 7 = 2x

SOLUTION: How do I solve this equation, 4x - 7 = 2x - 7 I added 7 to both sides, so it looks like this to isolate 4x on the left. 4x -7 + 7 = 2x - 7 + 7 Which gives me 4x = 2x- 7 +

Question 980346: How do I solve this equation,
4x - 7 = 2x - 7
I added 7 to both sides, so it looks like this to isolate 4x on the left.
4x -7 + 7 = 2x - 7 + 7
Which gives me
4x = 2x- 7 + 7
but -7 + 7 = 0 so I end up with
4x = 2x ?
Is this correct

.
4x-7=2x-7 Add 7 to each side.
4x=2x Subtract 2x from each side.
2x=0 Divide each side by 2.
x=0
.
CHECK:
4x-7=2x-7
4(0)-7=2(0)-7
-7=-7
