5x - y + 1 = 0
Factored, that's 4(5x + 1)(5x + 1) or 4(5x + 1)2 If the whole thing equals zero, x = -1/5
Multiply the bottom equation by -1
0 because X= -1
(1, 1)
Yes.

If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0
4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
x=1/5
(1, 0)
-5x+1 = 6x -5x-6x = -1 -11x = -1 x = 1/11
