Let x=lbs that sell for $2 and y=lbs that sell for $3.
\n" ); document.write( "x + y = 18
\n" ); document.write( "2x+3y=47
\n" ); document.write( ".
\n" ); document.write( "2x+2y=36 Multiply each side by 2.
\n" ); document.write( "2x+3y=47
\n" ); document.write( "--------subtract
\n" ); document.write( "-y=-11
\n" ); document.write( ".
\n" ); document.write( "y=11 lbs
\n" ); document.write( "x=7 lbs
\n" ); document.write( ".
