Answer:

5=y

Steps to solve question:


7 - 5y - 13 - y \\ 7 = 4y - 13 \\ 7 + 13 = 20 \\ 20 = 4y \\ / 4 = 4 \\ 5 = y

You are first going to put all like terms at one side and other like terms at the other side: 7+13=5y-y.
Next you will add like terms: 20=4y
Now you need to get the y by itself by dividing the 4 to both sides: 5=y and that would be your answer.
You should input the answer you get to make sure it’s correct:7=5(5)-13-5
Simplified all the way you would get: 7=7
This way you know that 5 is the correct answer for y.
