Question

The sum of Ken's, k, and Alan's, a, ages is 62. Ken is 31 years older than Alan.

Which of these systems of equations below best describes the ages of Ken and

Alan?

Answer 1

k + a = 62

k = 31 + a

Explanation:

Given that:

Sum of ken and Alan's age = 62

Ken is 31 years older than Alan

k + a = 62 - - - (1)

k = 31 + a - - - (2)

Hence, the system of equation which best describes the ages of Ken and Alan are:

k + a = 62

k = 31 + a
