Answer:

# y = 36 #

Explanation:

First, you want to have your variable and number on opposite sides of the equals sign so it can be easier to solve.

You can do this by adding 49 to both sides in order to cancel out 49 on the left side:

# y - 49 =-13 #
#+49 +49#

As you can see, y is on the left side of the equals sign, leaving the answer on the right hand side. After that you should obtain:

y = 36

You can check this answer by subtracting 49 from 36 and you will get -13:

36 - 49 =-13
