Question 834443
Let x = present age
age 6 years ago = x - 6
age 10 years hence = x + 10

Ten years from now her age will be triple what it was six years ago:
x + 10 = 3(x - 6)

3x - 18 = x + 10
3x = x + 28
2x = 28
x = 14;  She is age 14 at present.

Check:
14 + 10 =? 3 (14-6)
24 =? 3(8)
24 = 24 {{{check}}}
