An exam worth 145 points contains 50 questions. Some of the questions are worth two points and some are worth five points. How many two point questions are on the test? How many five point questions are on the test?

Re: Eh couldn't do this help plz?

Let x = number of 2point-questions; then 50-x = number of 5point-questions.

2x + 5(50 - x) = 145

Let's see you wrap that up, Max
