13y - 9y + 6 = 26
4y + 6 = 26
4y + 6 - 6 = 26 - 6 (we subtracted six from both sides so that the six on the left side cancels out and we are just left with 4y = 20.
4y = 20
4y/4 = 20/4 (we divided both sides by 4 because we needed to get rid of the four from our left side so that we would just be left with our x and our answer.
X = 5
