Answer:
A. 2y = 22
Explanation:
You are basically combining like terms. Look at the equation and subtract from top to bottom.
You will subtract 5x and 5x, 4y and 2y, and 25 and 3.
Now you have 0 + 2y = 22.
Removing the 0 (because it is worth nothing), you will be left with 2y = 22 which corresponds to A.
