For this math problem, you need to follow a few steps to solve for Y:
We need to isolate Y on to one side of the equation. Since we are adding 1/2 to Y, we would do the opposite-subtract 1/2-from both sides of the equation, in order to isolate and solve for Y.
We end up with this equation:
Y = -3/4 - 1/2. Convert 1/2 to 2/4ths, then do your math to solve for Y
