Question

Tony is 5 years older than Noelle. In 2 years the sum of their ages will be 69. How old is Tony now?

Answer 1

Note that:

• T = 5 + N
• T + 2 + N + 2 = 69

Substitute the given values into the equation.

• T + 2 + N + 2 = 69
• => 5 + N + 2 + N + 2 = 69
• => 2N + 9 = 69
• => 2N = 69 - 9
• => 2N = 60
• => N = 30
• => T = 5 + 30
• => T = 35

Tony is 35 years old.
