On Tuesday, I worked t+1 hours and earned 3t-3 dollars per hour. My friend Andrew worked 3t-5 hours but only earned t+2 dollars an hour. At the end of the day, I had earned two dollars more than he had. What is the value of t?

It says the answer is incorrect, do you know where you went wrong?

Solve for t:
(t + 1) (3 t - 3) - (t + 2) (3 t - 5) = 2

Expand out terms of the left hand side:
7 - t = 2

Subtract 7 from both sides:
-t = -5

Multiply both sides by -1:
t = 5
