You can put this solution on YOUR website!
x = number of nickels
\n" ); document.write( "y = number of dimes
\n" ); document.write( "---
\n" ); document.write( "5x + 10y = 170
\n" ); document.write( "y = x + 5
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "5x + 10y = 170
\n" ); document.write( "x - y = -5
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
