Step-by-step explanation:
Answer:
x = 24, y = 15
Step-by-step explanation:
Find attached the step-by-step solution.
The definition is pretty simple:

So, we only have to sum the expressions:

4 - 5x = 2x + 25
4 = 7x + 25
-21 = 7x
-3 = x
4 - 5x + 2x + 25 = ac
4 - 5(-3) + 2(-3) + 25 = ac
4 - (-15) + (-6) + 25 = ac
19 + (-6) + 25 = ac
38 = ac
