8x-8w = 0
9 8w - 17 = -89 ie 8w = -89 + 17 = -72 w = -9

w2 + 8w + 12 = (w + 6) (w + 2)
If X+Y = 42, and 2X + Y = 57, then if you subtract the first equation from the second, 2X + 1Y = 57 1X + 1Y = 42 - ---------------- 1X + 0Y = 15 That means that Y = 27. 15 + 27 = 42 15 + 15 + 27 = 57.
Combine like terms: 8w-6w = 2w -8-7 = -15 6w4w = 24w2 So, your expression is now: 24w2 + 2w - 15
8w - 12 = -48w = 8w = 1
9x - 8w = 1
8x-8w = 0
9x-8w = 1
8w x 5h = 40wh
If: 8w = 44 then w = 5.5
9 8w - 17 = -89 ie 8w = -89 + 17 = -72 w = -9
57 is 380% of 15.
