-6x - 29 + 7x = 8
Combine like terms on the left
x - 29 = 8
add 29 to both sides
x = 8 + 29
x = 37

-8x + 6x - 13 = 33
Combine like terms on the left
-2x - 13 = 33
add 13 to both sides
-2x = 46
divide both sides by -2
x = -23

First equation:
-6x-29+7x=8
Combine like terms
-6+7=1
1x-29=8
Add 29 to both sides
1x=37
Divide both sides by 1
x=37

Second equation:
-8x+6x-13=33
Combine like terms
-8+6=-2
-2x-13=33
Add 13 on both sides
-2x=46
Divide both sides by -2
x=-23
