Question 106835
{{{76433 = x+y}}}

{{{x- (15000) =2y }}} => {{{y = (x- 15000)/2}}}

Substitute {{{y}}} in first equation

{{{76433  = x + (x- 15000)/2}}}
{{{76433 = x + x/2 }}}– {{{7500}}}
{{{76433 + 7500 = 3/2 x}}}
{{{83933 = 3/2x}}}
{{{x  = 83933/(3/2)}}}

{{{x  =  83933/1.5}}}

{{{x =55955.33}}}
{{{y  = (55955.33- (15000))/2=  40955.33/2=  20477.67}}}
