\n" );
document.write( "Hi,
\n" );
document.write( "P/4=Q/2
\n" );
document.write( "P=3x and Q = (2-x)  Substituting for P and Q
\n" );
document.write( "
\n" );
document.write( "cross multiplying to solve for x
\n" );
document.write( "6x = 4(2-x)
\n" );
document.write( "6x = 8 - 4x
\n" );
document.write( "10x = 8
\n" );
document.write( "x = 8/10  Or x = 4/5 \n" );
document.write( "

\n" );
