if the sum of two numbers is {{{40}}} then

{{{x+y=40}}}... .....eq1

if the first number is {{{4}}} more than {{{two}}}{{{ times}}} the second number then

{{{x=2y+4}}}... .....eq2


substitute{{{x}}}


{{{2y+4+y=40}}}... .....eq1

{{{3y=40-4}}}

{{{3y=36}}}

{{{y=12}}}

go to

{{{x=2y+4}}}... .....eq2,substitute{{{y}}}

{{{x=2*12+4}}}

{{{x=28}}}

the two numbers are{{{12}}} and {{{28}}}
