Question 623177
Let Mark's age be n

Let Paul's age be n * 2 + 2 = 2n + 2

Combine their ages:

n + 2n + 2 = 32

Combine like terms:

n + 2n = 3n

3n + 2 = 32

Subtract 2 from each side of the equation

3n + 2 - 2 = 32 - 2

Combine like terms:

2 - 2 = 0

32 - 2 = 30

3n = 30

Divide each side by 3

3n/3 = 30/3

n = 10

2n + 2 = 2 * 10 + 2 

= 20 + 2 = 22

Therefore:

Mark is 10 years old and

Paul is 22 years old.
