Question

Which ordered pair (x, y) is a solution to the given system of linear equations?

3x+3y=-3
-2x+y=2

(–1, 0)
(0, –1)
(1, –2)
(1, 4)

Answer 1

(-1,0) is the answer

Answer 2

(-1, 0)

Start by adding -2x to both sides of the second equation. Then substitute that equation into the first.

3x+3(2x+2)=-3

Solve the equation for x.

When you've found the value of x, substitute that value into the equation with the isolated y.

y=2(-1)+2
