put this solution on YOUR website!Let S = Sarah's present age and D = Denise's present age.
From the problem description, you can write:
1)

"Sarah is 6 years more than 3 times as old as Denise"
2)

"In 14 years, the sum of their ages will be 82"
Substitute the S from equation 1) into equation 2) and solve for D.
2a)

Simplify.

Subtract 34 from both sides.

Divide by both sides by 4.

This is Denise's present age.

This is Sarah's present age.
