Question 1174388

The sum of Tina's age and her husband's age is 65. 25 years ago Tina's age was half of her husband's. How old is Tina?
<pre>Let Tina's age be T
Then the husband's is: 65 - T
This gives us: 65 - T - 25 = 2(T - 25)
40 - T = 2T - 50
- T - 2T = - 50 - 40
- 3T = - 90
Tina's age, or {{{highlight_green(matrix(1,5, T, "=", (- 90)/(- 3), "=", 30))}}}
