Question

What is the solution to the system of equations below?

y=-3x+3 and y=-12
(20, -12)
(12, -12)
(-6, -12)
(-12, 12)

Answer 1

(5, -12)

Explanation:

Put -12 in the equation for y and solve for x:

-12 = -3x +3

4 = x -1 . . . . . . . . divide by -3

5 = x . . . . . . . . . add 1

The solution to the system shown here is ...

(x, y) = (5, -12)
