Question

Isabel is three times as old as Nancy. The sum of their ages is 24. Which equation can be used to determine n, Nancy's age

Answer 1

6

Explanation:

Let Nancy's age be represented by n

Because Isabel is 3 times as old as Nancy, her age would be represented by 3n

Sum of their ages = 24

n + 3n = 24

4n = 24

divide both sides of the equation by 4 to determine n

n = 6
