Answer:
First, we can simplify the equation by bringing the variable terms (with y) to one side and the constant terms to the other side:
4 - 2y = 7y + 13
Subtracting 7y from both sides:
4 - 9y = 13
Subtracting 4 from both sides:
-9y = 9
Dividing both sides by -9:
y = -1
Therefore, y is equal to -1.
