\n" ); document.write( "

Let number of dimes be D, and number of quarters, Q
\n" );
document.write( "Then: .1D + .25Q = 5 ----- eq (i)
\n" );
document.write( "Also, D = Q + 8 ---------- eq (ii)
\n" );
document.write( ".1(Q + 8) + .25Q = 5 ------- Substituting Q + 8 for D in eq (i)
\n" );
document.write( ".1Q + .8 + .25Q = 5
\n" );
document.write( ".1Q + .25Q = 5 - .8
\n" );
document.write( ".35Q = 4.2
\n" );
document.write( "Q, or number of quarters = , or 
\n" );
document.write( "You should be able to find D: the number of dimes. \n" );
