Question

Find the solution to the system of equations.


−2x+2y=−4
3x+3y=−18
​

Answer 1

Set the equations equal to each other like this: -2x+2y=-4=3x+3y=18

Answer 2

x = -2

y = -4

Explanation:

To find the y-intercept, substitute the x with 0. To find the x-intercept, substitute the y with 0. You can then graph the lines using these intercepts, and see that they intercept at (-2, -14).
