let x be the cost of the shirt and y be the cost of the tie
\n" ); document.write( ":
\n" ); document.write( "x=y+15........eq 1
\n" ); document.write( "x+y=85........eq 2
\n" ); document.write( ":
\n" ); document.write( "take x's value from eq 1 and plug it into eq 2
\n" ); document.write( ":
\n" ); document.write( "(y+15)+y=85
\n" ); document.write( ":
\n" ); document.write( "2y=70
\n" ); document.write( ":
\n" ); document.write( "$ $\"highlight%28y=35%29\"$ cost of tie
\n" ); document.write( ":
\n" ); document.write( "$ $\"highlight%28x=35%2B15=50%29\"$ cost of shirt \n" ); document.write( "
