x=8, y=-10

Step-by-step explanation:

Using elimination to solve a system of equations works by manipulating one of the equations so you can cancel out a variable to solve the other.

Here, we can change -3x-2y=-4 into -15x-10y=-20 by multiplying by 5. Because of this, we can eliminate the y variable and end up with -5x=-40 which gets you x=8.

Now, we plug x=8 into one of the original equations and solve for y:

10x+10y=-20

10(8)+10y=-20

80 + 10y = -20

10y = -100

y = -10
