age differance

Question

Marissa and Kendra are 2 years apart in age. Their ages are two consecutive even integers. Kendra is the younger of the two. If Marissa's age is added to twice Kendra's age, the result is 20. How old is each girl?

Answer 1

Kendra's age = x

So Marissa's age = x+2

twice Kendra's age =2x

Marissa's age is added to twice Kendra's age, the result is 20.

x+2 + 2x = 20

3x =18

x=6

Kendra's age = x =6
So Marissa's age = x+2 =8
