\n" ); document.write( "Equations:
\n" ); document.write( "r + c = 17 flowers
\n" ); document.write( "1.50r + 0.80c = 19.20
\n" ); document.write( "----------
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "15r + 15c = 15*17
\n" ); document.write( "15r + 8c = 192
\n" ); document.write( "--------
\n" ); document.write( "Subtract and solve for \"c\"::
\n" ); document.write( "7c = 63
\n" ); document.write( "c = 9 (# of carnations bought)
\n" ); document.write( "r = 17-9 = 8 (# of roses bought)
