Ralph is 10 years younger than 3 times Rick's age. If Ralph is 53 years old, how old is Rick?

Let Rick's age =A

Ralph's age     =3A - 10

   53                  =3A - 10

3A = 63

A =63 / 3 = 21 years - Rick's age.

Ralph is 10 years younger than 3 times Rick's age. That means Rick is younger than Ralph.

 

Let's add Ralphs age by 10 to find out 3 * Rick's age: 53 + 10 = 63.

 

63 is  3 * Rick's age. Divide by 3 = Rick's age.

 

63 / 3 = 21.

Rick is 21 years old.
