Solve by elimination by filling in the blanks below. We will cancel our x's in this problem!

-5x+4y=30

2x+3y=-12

(x, y)=(0, -6）

Step-by-step explanation:

To solve a system of equations there are usually 3 general ways.

- Elimination

- Substitution

- Augmented Matrix

Since the question is asked to use elimination, we are going to use it.

-5x+4y=30

2x+3y=-12

-10x+8y=60

10x+15y=-60

23y=0

y=0

Substitute the y value into any one of the equations

2x+3y=-12

2x+3(0)=-12

2x+0=-12

x=-6

Hope this helps!! :)
