Assuming you mean 3x - 2 = 9x - 5...
3x - 2 = 9x - 5
3x + 3 = 9x
3 = 6x
0.5 = x

9x2-9x-10 = (3x+2)(3x-5) when factored
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
This simplifies to 6x = -3, so x = -0.5 Check: (3 x -0.5) + 2 = (9 x -0.5) + 5 ie -1.5 + 2 = -4.5 + 5 0.5 = 0.5 QED3x + 2 = 9x + 5 3x - 9x + 2 - 2 = 9x - 9x + 5 - 2-6x = 3 -6x/-6 = 3/-6 x = -1/2 or x = -0.5
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5
3x - 5 = 2y3/2X - 5/2 = y
