I can help with CL 2-107. All you have to do is simplify the equation on both sides, and then isolate <em>w</em> to find its value.
6w - 5 + 8w - 2w - 3 = 9w - 24
(-5) + 12w - 3 = 9w - 24
-8 + 12w = 9w - 24
-8 + 3w = -24
3w = -16
w =
w = -5.33
Hope that helps! Sorry I couldn't help with the other ones!
