6x - 13y
Step-by-step explanation:
5(2x - 2y) - (4x + 3y)
10x - 10y - 4x - 3y
10x - 4x - 10y - 3y
6x - 13y
Step-by-step explanation:
I think we cannot find the sum because it will continue on so the series is multiply by 4
Answer:
x = 12
Step-by-step explanation:

Divide each side by 5
5x/5 = 60/5
x = 12
