Some plusses or minusses would help, but here goes anyway: 2y2 - 6y - 8 = (2y + 2)(y - 4); y = -1 or 4 2y2 + 6y - 8 = (2y - 2)(y + 4); y = 1 or -4

6(y - 4)
8x = 6y (8/6)x = y (4/3)x = y Let x = 3, 6, and 9, then y = 4, 8, and 12. So that for any value of x, you will find a correspoinding value for y.

6y-1+8=32 y=4 1/6 Here's the steps- 6y-1+8=32 6y+7=32 6y=25 y=4 1/6
6y + 8 = 32 6y + 8 - 8 = 32 - 8 6y = 24 6y/6 = 24/6 y = 4

6y = 3x + 4 y = 3/6x + 4/6 or y = x/2 + 2/3

As written, that's 17y + 4 which is in its simplest form. -6y^2 + 23y + 4 factors to (4 - y)(1 + 6y)
