Answer 1

4

Explanation:

1. Substitute the x value of -9 into the equation:

6(-9) + 9y = -18

2. Simplify

-54+9y = -18

3. Add 54 to both sides to get 9y by itself, the goal is to get y by itself

9y = 36

4. Divide by 9 on both sides to get y completely by itself

y = 4

Answer 2

4

Explanation:

Just plug in -9 to the equation

6(-9) + 9y = -18

-54 + 9y = -18 isolate 9y

54 - 54 + 9y = -18 + 54

9y = 36 isolate y

9y/9 = 36/9

y = 4
