SOLUTION:
6. x + 27 = 35 - 12
x + 27 = 23
x + 27 - 27 = 23 - 27
x = -4
7. -41 + 3x = -41
-41 + 3x + 41 = -41 + 41
3x = 0
x = 0
8. I'm not sure about this, so my answer maybe wrong
-45 - 13 = -58
77 + 90 = 167
-58 = 167 False: The sides are not equal
9. -5g + 32 = -13
-5g + 32 - 32 = -13 -32
-5g = -45
g = 9
10. I'm also not sure about this, so my answer maybe wrong
96 - 46 = 50
50 = -28 False: The sides are not equal
