Let x= number of nickels @ 5 cents
\n" ); document.write( "50-x = number of dimes @ 10 cents\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The equation is
\n" ); document.write( "5x+10(50-x) = 350 cents
\n" ); document.write( "5x+ 500-10x=350
\n" ); document.write( "-5x=350-500
\n" ); document.write( "-5x=-150
\n" ); document.write( "x=30 Nickels
\n" ); document.write( "50-30= 20 Dimes\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( ".05(30)+.10(20)=
\n" ); document.write( "1.50+2.00
\n" ); document.write( "$3.50\r
