N+D=50 N=50-D
\n" ); document.write( "5N+10D=350 NOW SUBSTITUTE (50-D) FOR N IN THIS EQUATION & SOLVE FOR D
\n" ); document.write( "5(50-D)+10D=350
\n" ); document.write( "250-5D+10D=350
\n" ); document.write( "5D=350-250
\n" ); document.write( "5D=100
\n" ); document.write( "D=20 NUMBER OF DIMES.
\n" ); document.write( "N+20=50
\n" ); document.write( "N=30 NUMBER OF NICKELS
\n" ); document.write( "PROOF
\n" ); document.write( "5*30=10*20=350
\n" ); document.write( "150+200=350
\n" ); document.write( "350=350
\n" ); document.write( "
