\n" ); document.write( "x=number of snowboards; y=number of skis
\n" ); document.write( "x+y=28
\n" ); document.write( "x=28-y Use this to substitute for x.
\n" ); document.write( ".
\n" ); document.write( "$19x+$16y=$478 Substitute for x from above.
\n" ); document.write( "$19(28-y)+$16y=$478
\n" ); document.write( "$532-$19y+$16y=$478
\n" ); document.write( "-$3y=-$54
\n" ); document.write( "y=18 ANSWER 1: 18 members rented skis.
\n" ); document.write( "x=28-y=28-18=10 ANSWER 2: 10 members rented snowboards.
\n" ); document.write( ".
\n" ); document.write( "CHECK:
\n" ); document.write( "$19x+$16y=$478
\n" ); document.write( "$19(10)+$16(18)=$478
\n" ); document.write( "$190+$288=$478
\n" ); document.write( "$478=$478\r
