Question

Jerry is 5 years less than half of Mary's age. The sum of their ages is 22. How old is each person?

Answer 1

Equation 1: m/2 - 5 = j

Equation 2: m + j = 22

Mary's age: 18

Jerry's age: 4

Explanation:

m/2 - 5 = j

18/2 - 5 = j

9 - 5 = 4

m + j = 22

18 + 4 = 22

22 = 22

Answer 2

Mary= 18

Jerry = 4

Explanation:

Half of mary's age is 9, minus 5 =4.
