Question

Isaac is younger than Genesis. Their ages are consecutive integers. Find Isaac's age if the sum of Isaac's age and 4 times Genesis's age is 59.

Answer 1

Let's denote Genesis' age as x (an integer), which makes Isaac's age x - 1 (as their ages are consecutive integers).

Now, we're given that the sum of Isaac's age and 4 times Genesis' age is 59:

x-1+4x=59

Solving for x, we get:

x-1+4=59

5x-1 =59

5x=60

x=12

Genesis' age (x) is 12, and Isaac's age (x-1) is 11
