\n" );
document.write( "I.   2s+1p=$55
\n" );
document.write( "II.  1s+2=$68   |Note used variable s rather than p\r
\n" );
document.write( "\n" );
document.write( " 2s+1p=$55
\n" );
document.write( "-2s - 4p = -$136     |Multiplying EQ II thru by -2 and adding to the 1st to eliminate s  (68*(-2) = -136)
\n" );
document.write( "        -3p = - $81, 
\n" );
document.write( "         p = $27, the cost of the slacks  
\n" );
document.write( "      s = $14,cost of a shirt
