Question

A father is 4 times as old as his son. Two years ago, the sum of their ages was 51 years. How old is the son?

Answer 1

Answer:

+4X = 50 we call this equation 1

solving for X in equation 1

X+4X = 50

5X= 50, Divide both sides by 5

5X÷5= 50÷5

X=10

The son's age X = 10

The father's age is 4X= 4x10= 40

Checking. ..

10+40=50
