Twice as many dimes as nickels,
\n" ); document.write( " $\"D=2N\"$
\n" ); document.write( "A dollar in dimes and nickels,
\n" ); document.write( " $\"0.1D%2B0.05N=1\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"D-2N=0\"$
\n" ); document.write( " $\"0.1D%2B0.5N=1\"$
\n" ); document.write( "So the augmented matrix would be,
\n" ); document.write( " $\"%28matrix%282%2C3%2C1%2C-2%2C0%2C0.1%2C0.5%2C1%29%29\"$ \n" ); document.write( "

\n" );
