Answer:

y = 5

Step-by-step explanation:

The equation 5x − 2y = 30 tells us that if we take 5 times x and subtract 2 times y, the answer will be 30.  If we know either x or y, we can solve for the other.

We are given that x=8.  Use the 8 for x in the equation:

5x − 2y=30  

5*(8) − 2y=30

40 − 2y=30

-2y = -10

y = 5
