We are given that Terrence scored (90x - 20) points, and that he scored 20 points less than Shelly. Therefore, Shelly scored (90x - 20) + 20 = 90x.
Since the first term of the expression is 90x, this is equivalent to the number of points Shelly earned. Therefore the best answer is the first choice.
