\n" ); document.write( "

Let time Karen takes be H
\n" );
document.write( "Then time Phoebe takes = H  -  4
\n" );
document.write( "And, Karen and Phoebe can do  of job in 1 hour, respectively
\n" );
document.write( "We then get:  ======>  ======> 
\n" );
document.write( "8(H  -  4) + 8H = 3H(H  -  4) -------- Multiplying by LCD, 3H(H  -  4)
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "3H(H  -  8) - 4(H  -  8) = 0
\n" );
document.write( "(H  -  8)(3H - 4) = 0_____H - 8 = 0         OR          
\n" );
document.write( "H, or time Karen takes: 
\n" );
document.write( "Time Phoebe takes:  \n" );
