Mehmut is 4 times as old as his brother, but
next year he will be only 3 times as old. Find
Mehmut's age now?
Solution
Let M = Mehmut
Let b = brother
M = 4b
When the question states "...but
next year he will be only 3 times as old" I am thinking of adding 1 to Mehmut and his brother (number 1 representing one more year).
Anyway, here is my set up:
M = 4b
M + 1 = 3(4b + 1)
Correct set up?
