Answer:
Daughter's present age = 42 years
Women's present age = 84 years
Step-by-step explanation:
Daughter's present age = x years
Women's present age = 2*x = 2x
21 years ago:
Daughter's age = x - 21
Women's age = 2x - 21
Women's age = 3*daughter'sage
2x - 21 = 3*(x - 21)
2x - 21 = 3x - 63 {Subtract '2x' from both sides}
- 21 = 3x - 2x - 63
-21 = x - 63 {Add 63 to both sides}
-21 +63 = x
42 = x
Daughter's present age = 42 years
Women's present age = 2*42 = 84 years
