MHB What is the present age of the mother and son in this age problem?

[mathdad]

A mother is 10 times as old as her son. In six years time she will be four times as old as her son. Find the present age of the mother.

Here is the set up:

Mother = 10x

Son = x

10x + 6 = 4(x + 6)

Correct?

Complete the problem and check your work to find out! :)

10x + 6 = 4(x + 6)

10x + 6 = 4x + 24

10x - 4x = 24 - 6

6x = 18

x = 18/6

x = 3

So, the son is 3 and his mom is 30.
