Question

Solve the following system of equations: y = 3x – 2 6x – y = 2

Answer 1

well you know that y = 3x - 2. So sub 3x - 2 in for y in the other equation and solve for x.

Answer 2

once subbed in, it looks like this...
6x - y = 2
6x - (3x - 2) = 2 -- distribute through the parenthesis
6x - 3x + 2 = 2
3x = 0
x = 0

6x - y = 2
6(0) - y = 2
-y = 2
y = -2

check...
y = 3x - 2
-2 = 3(0) - 2
-2 = -2 (correct)

x = 0 and y = -2
