You can put this solution on YOUR website!
x = nickels
\n" ); document.write( "y = quarters
\n" ); document.write( "---
\n" ); document.write( "x + y = 50
\n" ); document.write( "5x + 25y = 630
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
