Question 765952
We will call the numbers x and y; x being the smaller number and y being the larger number. Then the following equations arise:

{{{x+y=54}}}
{{{2x=y+6}}}

Now this is a standard 2x2 linear system we can solve:

{{{x+y=54}}}
{{{2x-y=6}}}

Add the equations:

{{{3x=60}}}
{{{x=20}}}

So x=20, and thus y=34
