Practice elimination by solving the following systems᠎᠎
-4-2y=-12
4+8y=-24

y = -6

Step-by-step explanation:

-4-2y=-12

4+8y=-24

We can eliminate 4.

4+8y-4-2y = -12-24

Simplify.

6y = -36

Find y.

y = -36 ÷ 6

Simplify.

y = -6

-4-2y=-12

4+8y=-24

by elimination method,

-4 - 2y = -12

4 + 8y = -24

0 + 6y = -36

6y = -36

y = -36/6

y = -6
