19w + 13 - 10 + 8w + 7
= 27w +20 - 10
= 27w + 10
answer: 27w+10
-2w+ 10 = 8w- 10
W=5
Simplified, this is equal to 19 + 8w = 67 Therefore, 8w = 67 - 19 = 48 Therefore, w = 48/8 w = 6
5w + 9.9 = 4.8 + 8w5w - 5w + 9.9 - 4.8 = 4.8 - 4.8 + 8w - 5w5.1 = 3w5.1/3 = 3w/31.7 = w
2w + 16 = - 6w - 8 2w + 16 + 6w = - 8 8w + 16 = - 8 8w = - 8 - 16 8w = - 24 w = - 3
-36 + 2w = -8w + w -36 + 2w = -7w -36 = -7w - 2w -36 = -9w w = -36/-9 = 4
A simple equation, true when w = -4
8w - 12 = -48w = 8w = 1
9x - 8w = 1
8x-8w = 0
9x-8w = 1
56w2 + 17w - 3 = 56w2 + 24w - 7w - 3 = 8w(7w + 3) - 1(7w + 3) = (7w + 3)(8w - 1)
