Cameron is 7 years older than Alexis. In 6 years the sum of their ages will be 57. How old is Cameron now?

## Answer provided by our tutors

Let

x = the current age of Alexis

y = the current age of Cameron

Cameron is 7 years older than Alexis means:

y = x + 7

In 6 years the sum of their ages will be 57 means:

(x + 6) + (y + 6) = 57

We need to solve the following system of equations:

y = x + 7

(x + 6) + (y + 6) = 57
