Basic Word Problem in Mathematics

Basic Algebra: Word Problem.

If Psalm is twice as old as Mike and Mike is 2 years older than Ford, how old are they if the sum of their ages is 42?

Solution:

Let

x = age of Mike

2x = age of Psalm

x-2 = age of Ford

Hence,

x + (2x) + (x-2)= 42

4x – 2 = 42

4x = 44

x = 11 > the age of Mike

2x = 22 > the age of Psalm

(x-2) = 9 > the age of Ford.
