Nickels=x
\n" ); document.write( "Dimes=29-x
\n" ); document.write( "Total value of all coins= $2.40\r
\n" ); document.write( "\n" ); document.write( "(Nickels)(Value of a Nickel)+(Dimes)(Value of a Dime)=Total value of all coins
\n" ); document.write( "(x)(0.05)+(29-x)(0.1)=2.40
\n" ); document.write( "0.05x+2.9-0.1x=2.40
\n" ); document.write( "0.05x-0.1x=2.40-2.9
\n" ); document.write( "-0.05x=-0.5
\n" ); document.write( "-0.05x/-0.05=-0.5/-0.05
\n" ); document.write( "x=10\r

\n" ); document.write( "\n" ); document.write( "Nickels=x=10
\n" ); document.write( "Dimes=29-x=29-10=19\r
