Question 135700
Let x be the smaller number and y be the larger one.

{{{x + y = 2y -4}}}
{{{x + 4 = y}}}

{{{y - 3x = -20}}}   sub for y using the value above

{{{(x+4) - 3x = -20}}}
{{{ -2x + 4 = -20}}}
{{{ -2x = -24 }}}
{{{x = 12}}}

Which means y = 16

Check your answer. Is (12+16) = (32-4)??? yes it is!
