8x - 9 = 11x + 12 8x = 11x + 21 -3x = 21 x = -7
(8x + 3)2 ie (8x + 3)(8x + 3)
6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
8x + x = 9x
-8x-9+(-18) -8x-9-18 -8x-27 is your simplified answer
8x - 9 = 9x - 5 8x - 8x - 9 = 9x - 8x - 5 -9 = x - 5 -9 + 5 = x - 5 + 5 -4 = x
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
x^2 - 8x - 9
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:

If: -9-4x = 7-8x Then: x = 4
This would be easier with operational signs but assuming everything is added together, the answer is (8x + 9)(8x + 9) or (8x + 9)2
8x - 9 = 11x + 12 8x = 11x + 21 -3x = 21 x = -7
8x-3=6 8x=9 x=9/8=1 1/8=1.125
8x-2 = -9+7x8x-7x = -9+2x=-7
(8x + 9)(3x^2 - 1)
