A student takes a 50-question test. Each question is worth 2 points. That means the whole test is worth 100 points, and the student loses 2 points for every question missed.

Write an expression to find the student’s test score if they get x questions wrong.

If the student gets x questions wrong, then they would lose 2 points for each of those x questions. Therefore, the expression to find the student's test score would be:

100 - (2 * x)
