Answer: D-18 years, Joan-41 years

Step-by-step explanation:

Given

The Sum of Debbie and Joan's age is 59

Take x and y as the age of Debbie and Joan

In 5 years, twice Debbie's age will be equal to Joan's age

\Rightarrow 2(x+5)=y+5

\Rightarrow 2x+10=y+5\\\Rightarrow 2x-y=-5

Also, x+y=59

solving these two equations we get

\Rightarrow x=18;y=41
