Call the prices of shirts and slacks, x and y. Then we have
\n" ); document.write( "5x + 3y = 172 and
\n" ); document.write( "3x + 4y = 156
\n" ); document.write( "Let's multiply the top by 3 and the bottom by 5 and subtract them, giving us
\n" ); document.write( "15x + 9y = 516
\n" ); document.write( "-(15x + 20y = 780)
\n" ); document.write( "------------------
\n" ); document.write( "-11y = - 264
\n" ); document.write( "y = $24 for slacks, then
\n" ); document.write( "5x + 3(24) = 172
\n" ); document.write( "5x + 72 = 172
\n" ); document.write( "5x = 100
\n" ); document.write( "x = $20 for shirts
\n" ); document.write( "
\n" );
