\n" ); document.write( "x=dimes
\n" ); document.write( "x +10= nickels
\n" ); document.write( "90-2x= quarters
\n" ); document.write( "-----------------
\n" ); document.write( "What you have is correct.
\n" ); document.write( "Then add:
\n" ); document.write( "10*x + 5*(x+10) + 25*(90-2x) = 1180
\n" ); document.write( "You can do it from here, I'm sure, but...
\n" ); document.write( "10x + 5x+50 + 2250-50x = 1180
\n" ); document.write( "-35x = -1120
\n" ); document.write( "x = 32 dimes (= $3.20)
\n" ); document.write( "42 = nickels (= $2.10)
\n" ); document.write( "26 = quarters (= $6.50)
\n" ); document.write( "100 coins------$11.80\r
\n" ); document.write( "
