Answer:
Step-by-step explanation:
Equation
5y = 3y + 4
combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.
-3y + 5y = 4
After adding a low negative to a high positive number. Turns into 2y.
2y = 4
Divide 2 on both sides to remove the number from the variable on the left.
y = 
2 is canceled on the left side which gives the solution for Y.
y = 2
-5 is the answer to your question because all you do is plug in -2 into your equation for x
