You can put this solution on YOUR website!
x = nickels
\n" ); document.write( "y = dimes
\n" ); document.write( "---
\n" ); document.write( "x + y + 1 = 10
\n" ); document.write( "5x + 10y + 25*1 = 90
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 9
\n" ); document.write( "5x + 10y = 65
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
