Question

The sum of the ages of a woman and her son is 36 years. Six years from now the woman will be twice as old as her son. How old is she now?

Answer 1

Let the age of the woman=w
And the son=s

Answer 2

s+w=36

Answer 3

Other equation

6+w= 2(s+6)

Answer 4

Subtract w on both sides in equation 1

So s=36-w

And substitute this into second equation and solve for w
