3x-2y=3
\n" ); document.write( "-2y=-3x+3
\n" ); document.write( "y=-3x/-2+3/-2
\n" ); document.write( "y=3x/2-3/2
\n" ); document.write( "25x+10y=215
\n" ); document.write( "25x+10(3x/2-3/2)=215
\n" ); document.write( "25x+30x/2-30/2=215
\n" ); document.write( "25x+15x-15=215
\n" ); document.write( "40x=215+15
\n" ); document.write( "40x=230
\n" ); document.write( "x=230/40
\n" ); document.write( "x=5.75 ans.
\n" ); document.write( "y=3*5.75/2-3/2
\n" ); document.write( "y=17.25/2-3/2
\n" ); document.write( "y=14.25/2 ans.
\n" ); document.write( "y=7.125 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "25*5.75+10*7.125=215
\n" ); document.write( "143.75+71.25=215
\n" ); document.write( "215=215
\n" ); document.write( " \n" ); document.write( "
