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
