For this problem, you would substitute into
So, here's how it would look:

Now solve through order of operations:

Now, combine like terms (add the y's together)

Next, you would get y by itself by subtracting the 50 from the left side to the right side of the equation.

Then, add 13 and 50, keep the negative sign (both #'s are negative)

Next, divide -21 onto both sides of the equation.

3 is positive because a negative divided by a negative is positive.
Hope that helps.
