(3x-2)(x-2)
If: 15+3x = 6x-2 Then: 15+2 = 6x-3x => 17 = 3x Therefore: x = 17/3 or 5 and 2/3 as a mixed number
Assuming you mean 3x - 2 = 9x - 5...3x - 2 = 9x - 53x + 3 = 9x3 = 6x0.5 = x
3x-1 = 7 3x = 8X= 8/3 = 2+2/3
-3X+Y = 2 becomes Y = 2+3X -9X + 2Y =2 becomes -9X + 2(2+3X) =2, which we can now solve. -9X + 4 + 6X = 2 -3X = -2 X = 2/3 Going back to our original equation: Y = 2+3(2/3) Y = 4
(3x-2)(x-2)
-2/15 or pronounced negative two fifteenths
If you mean y=3x-2, you can solve for x as follows: 3x-2+2 = y+2, x = (y+2)/3 = y/3 + 2/3
It is negative 3x^2.

1) 3x-17=0 3x=17 x=17/3 2) 3x-25=0 3x=25 x=25/3
3x - 4 = -2 The answer is x=2/3

3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
6x2 = -7x -2 6x2 + 7x + 2 = 0 6x2 + 3x + 4x + 2 = 0 3x(2x + 1) + 2(2x + 1) = 0 (2x + 1)(3x + 2) = 0 2x + 1 = 0 or 3x + 2 = 0 So, x = -1/2 or -2/3
If: 15+3x = 6x-2 Then: 15+2 = 6x-3x => 17 = 3x Therefore: x = 17/3 or 5 and 2/3 as a mixed number
