Question 201494
You'll need three statements.
Let {{{A - B = x}}} This represents how many years ago that A was the age B is now.

Then
{{{(A-x) = 2(B-x)}}} This is the equation for the second sentence

So
{{{A-x = 2B - 2x}}}
{{{A - 2B = -x}}}
{{{A- B = x}}}
------------------
{{{2A - 3B = 0}}}
{{{A   + B = 98}}}

I bet you can solve it from here :)

I get A=58.8 B=39.2
