cost of watches=w
\n" ); document.write( "cost of clocks=c
\n" ); document.write( "-----------------------------
\n" ); document.write( "8c + 5w = 695
\n" ); document.write( "3c + 3w = 300
\n" ); document.write( "-----------------------------
\n" ); document.write( "combine:
\n" ); document.write( "24c + 15w = 2085
\n" ); document.write( "-15c - 15w = -1500
\n" ); document.write( "9c = 585
\n" ); document.write( "c = 65
\n" ); document.write( "----------------------------
\n" ); document.write( "3c + 3w = 300
\n" ); document.write( "3(65) + 3w = 300
\n" ); document.write( "195 + 3w = 300
\n" ); document.write( "3w = 105
\n" ); document.write( "w = 35 \n" ); document.write( "
