the present age of a women is three years more that three times the age of her daughter.
---
m = 3d
---
three years hence, the womans age will be ten years more than twice the age of her daughter.
---
(m+3) = 2(d+3)+10
---
find their present ages.
---
Substitute for "m" and solve for "d":
(3d+3) = 2(d+3)+10
3d+3 = 2d+6+10
d = 13 (daughter's age NOW)
---
Since m = 3d, m = 39 (mother's age NOW)
