Question 1153652
Jason's age is 3 times Shauna's present age.In 4 years' time, the sum of their ages will be 56 years. Find their present age
<pre>Let Shauna's age be S
Then Jason's is: 3S
We then get: S + 3S + 2(4) = 56
4S = 48
S, or Shauna is: {{{highlight_green(matrix(1,4, 48/4, "=", 12, years-old))}}}
It's now simple as 1-2-3 to find Jason's age!
Using 1 variable is most often much easier and less confusing than using 2!!
