T + S = 68
\n" ); document.write( "T = 3S
\n" ); document.write( "Substitute the known value of T from the second equation into the first.
\n" ); document.write( "(3S) + S = 68
\n" ); document.write( "4S = 68
\n" ); document.write( "Divide each side by 4
\n" ); document.write( "S = 17
\n" ); document.write( ".
\n" ); document.write( "If the shirt costs R17, then the trousers cost 3*R17, or R51.
\n" ); document.write( "
