Let rene age=x years.

So, Adrienne age=2x years.

3 years ago, Rene's age=x-3 years and Adrienne's age=2x-3

So, x-3+2x-3=48

3x-6=48

3x=54

x=18

Rene's age=18 years and Adrienne's age=36 years

Adrienne is twice as old as rene.

a. Let Rene's age be represented by ____ years.

b. Then Adrienne's age is ____ years.

c. The sum of their ages 3 years ago was 48.

 

The answer:

Rene=x years, 

Means, Adrienne=2x years

3 years ago the sum of their age is 48

so...

(x-3)+(2x-3)=48

x+2x-3-3=48

3x-6=48

3x=48+6

3x=54

x=18

Rene=x=18

Adrienne=2x=18.2=36
