2x+3y=227
\n" ); document.write( "x+y=76 multiply by -2 & add
\n" ); document.write( "-2x-2y=-152
\n" ); document.write( "2x+3y=227
\n" ); document.write( "-------------------
\n" ); document.write( "y=75 tricycles.
\n" ); document.write( "x+75=76
\n" ); document.write( "x=76-75
\n" ); document.write( "x=1 bicycle.
\n" ); document.write( "Proof:
\n" ); document.write( "2*1+3*75=227
\n" ); document.write( "2+225=227
\n" ); document.write( "227=227\r
