g Geneross


{{{system(c+j+g-15=(13/25)(c+j+g+9),g=c-5,c=j+2)}}}


{{{system(25c+25j+25g-15*25=13c+13j+13g+117,g=c-5,j=c-2)}}}


{{{system(12c+12j+12g=15*25+117,g=c-5,j=c-2)}}}


{{{system(12c+12j+12g=492,g=c-5,j=c-2)}}}


{{{system(c+j+g=41,g=c-5,j=c-2)}}}


Substitute for g and j into the first equation and have one equation all in one single variable, c.

{{{highlight_green(c+(c-2)+(c-5)=41)}}}
