Answer:

(8,5)

Step-by-step explanation:

x=8,

5(8)-2y=30

40-2y=30

40-30=2y

10=2y

y=10/2

y=5

Answer:

y=5

Step-by-step explanation:

If x=8, you plug it in and the equation is 5(8)-2y=30. If you solve it further, it is 40-2y=30. If you ignore the 2y for now, 40 minus what equals 30? The answer is 10 so you look at 2y and determine how you can multiply 2 to get 10. The answer is 5 so the full equation is 40-10=30.
