Question

Jonathan is 6 years older than twice his sister Margo's age. How old is the age of each person

if the sum of their ages is 45?

Answer 1

• Jonathan: 32
• Margo: 13

Explanation:

Let m represent Margo's age. Then Jonathan's age is 6+2m, and the sum of their ages is ...

m + (6+2m) = 45

3m = 39 . . . . . . . . . subtract 6

m = 13 . . . . . . . . . . . divide by 3

45 -13 = 32

Margo's age is 13; Jonathan's age is 32.
