Step-by-step explanation:

Let a represent the the number of math problems that Olivia solved.

Let b represent the number of pages she read.

Olivia had math and reading homework tonight. Olivia can solve each math problem in 1 minute and she can read each page in 1.5 minutes. This means that she can solve a math problems in a minutes and read b pages in 1.5b minutes.

Olivia completed a total of 22 math problems and pages of reading in 30 minutes. This means that

a + 1.5b = 30

She completed a total of 22 math problems and pages of reading. This means that

a + b = 22
