4s+3p=85.50 multiply this equation by 3.
\n" ); document.write( "3s+5p=115.00 multiply this equation by -4 & add them.
\n" ); document.write( "12s+9p=256.50
\n" ); document.write( "-12s-20p=-460
\n" ); document.write( "-------------------
\n" ); document.write( "-11p=-203.5
\n" ); document.write( "p=-203.50/-11
\n" ); document.write( "p=$18.50 is the price of each pair of pants.
\n" ); document.write( "4s+3*18.50=85.50
\n" ); document.write( "4s+55.50=85.50
\n" ); document.write( "4s=85.50-55.50
\n" ); document.write( "4s=30
\n" ); document.write( "s=30/4
\n" ); document.write( "s=$7.50 is the price of each shirt.
\n" ); document.write( "Proof:
\n" ); document.write( "3*7.50+5*18.50=115.00
\n" ); document.write( "22.50+92.50=115.00
\n" ); document.write( "115.00=115.00
\n" ); document.write( "
\n" );
