Answer:

y = -2, y = -5, x = 20, x = -12

Explanation:

When dealing with unknown y values, rearrange the equation so that y is isolated:

y + 5 = x/4 >>> subtract 5 from both sides >>> y = x/4 - 5

Now, substitute in your values for y in the table:

12/4 - 5 = -2

0/4 - 5 = -5

Now, to deal with unknown y values, rearrange so that y is instead isolated:

y + 5 = x/4 >>> multiply both sides by 4 >>> 4y + 20 = x

Substitute!

4(0) + 20 = 20

4(-8) + 20 = -12
