mechanic a makes x dollars per hour
\n" ); document.write( "mechanic b makes y dollars per hour.
\n" ); document.write( "10x+15y=2175
\n" ); document.write( "x+y=160; multiply this by -10 and add to the first to eliminate x
\n" ); document.write( "-10x-10y=-1600
\n" ); document.write( "5y=575
\n" ); document.write( "y=$115 @ 15 hours=$1725
\n" ); document.write( "x=$45 @ 10 hours=$450
\n" ); document.write( "They add to $2175.
\n" ); document.write( " \n" ); document.write( "
