Question 1152214

Alison is 26 years younger than her father. Her father’s age will be 3 time her age in 4 years’ time. How old is Alison
<pre>Let Alison's age be A
Then father's is: A + 26
We then get: A + 26 + 4 = 3(A + 4)
A + 30 = 3A + 12
A - 3A = 12 - 30
- 2A = - 18 
Alison's age, or {{{highlight_green(matrix(1,6, A, "=", (- 18)/(- 2), "=", 9, years-old))}}}
