Answer:

Answer below!

Explanation:

since y = -3x + 1, you can just plug those numbers in on the first equation.

6x + 2(-3x+1) = 2 (see how I replaced y into -3x + 1)

then distribute 2.

6x - 6x + 2 = 2, subtract 2 to both sides

6x - 6x = 0, combine x

0 = 0 (this means it has an infinite amount of solutions)
