2(x - 3) - 3(x + 5) = 3(x - 2) - 7
2x - 6 - (3x + 15) = 3x - 6 - 7
2x - 6 - 3x - 15 = 3x - 13
- x - 21 = 3x - 13
- x - 21 + x = 3x - 13 + x
- 21 = 4x- 13
- 21 + 13 = 4x - 13 + 13
- 8 = 4x
- 8 / 4 = 4x / 4
- 8 / 4 = x
- 2 = x

2(x - 3) - 3(x + 5) = 3(x - 2) - 7
=>2x-6 -3x -15 = 3x-6-7
=>-4x = 8
=>x= -2
verification...
=>2(-2-3)-3(-2+5)=3(-2-2)-7
=>-4-6+6-15=-6-6-7
=>-19=-19
verified....
yippeee....i did a sum...

Distribute and collect terms:
2x-6-3x-15 = 3x-6-7
-x-21=3x-13
-4x=8
x=-2
check: -10 - 9 = -12 - 7 Yep!

2(x - 3) - 3(x + 5) = 3(x - 2) - 7
or 2x-6-3x-15=3x-6-7
or -4x=21-13
or x=-8/4=-2

2(x - 3) - 3(x + 5) = 3(x - 2) - 7
2x - 6 - 3x - 15 = 3x - 6 - 7
2x - 3x - 3x = - 6 - 7 +6 +15
-4x = 8
x = -2
