Answer: x = 7
First you want to combine like terms:
x - 13 + 4x = 22
5x - 13 = 22
Next you want to add 13 to both sides:
5x - 13 = 22
5x - 13 + 13 = 22 + 13
You then want to simplify the expression:
5x - 13 + 13 = 22 + 13
5x = 22 + 13
22 + 13 = 35
5x = 35
Then you want to divide both sides by the same factor:
5x = 35
5x / 5 = 35 / 5
Then simplify the expression:
x = 7.
Correct answer is x = 7
