-6 + 4x + (9-2x) = -6 + 4x + 9 - 2x = [ 3 + 2x ]
(2x - 3)(4x + 9)(2x + 3) = (2x - 3)(2x + 3)(4x + 9) = [(2x)^2 - (3^2)](4x + 9) = (4x^2 - 9)(4x + 9) = (4x^2)(4x) + (4x^2)(9) - (9)(4x) - (9)(9) = 16x^3 + 36 x^2 - 36x - 81
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
2x = 4x + 3 -2x = 3 x = -3 / 2
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
2x + 4x + 3 = 6x + 3
-6 + 4x + (9-2x) = -6 + 4x + 9 - 2x = [ 3 + 2x ]
(2x - 3)(4x + 9)(2x + 3) = (2x - 3)(2x + 3)(4x + 9) = [(2x)^2 - (3^2)](4x + 9) = (4x^2 - 9)(4x + 9) = (4x^2)(4x) + (4x^2)(9) - (9)(4x) - (9)(9) = 16x^3 + 36 x^2 - 36x - 81
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
2x = 4x + 3 -2x = 3 x = -3 / 2
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
2x - 4x + 3 = 0 -2x + 3 = 0 2x = 3 x = 3/2 = 1.5
6X + 3 = 2X + 19Subtract 3 from each side:6X = 2X +16Subtract 2X:4X = 16Divide by 4X = 4
2x-3=4x+9 -2x-12=0 2x=-12 x=-6
5x + 3 - 4 + 4x = 9x -1
2x - 5 - 4x + 8= 2x - 4x - 5 + 8= -2x + 3
