Question 1152958
Stephen is 64 years younger than Wendy. 7 years ago, Wendy's age was 3 times Stephen's age. How old is Stephen now?
<pre>This is EXTREMELY SIMPLE....much, much SIMPLER than the other person makes it out to be. Plus, the question asks for STEPHEN'S AGE, not Wendy's!
Let Stephen's age be S
Then Wendy's is: S + 64
We then get: S + 64 - 7 = 3(S - 7)
S + 57 = 3S - 21
S - 3S = - 21 - 57
- 2S = - 78
S, or {{{highlight_green(matrix(1,6, Stephen, "is:", (- 78)/(- 2), "=", 39, years-old))}}}
