You can put this solution on YOUR website!
x = number of nickels
\n" ); document.write( "y = number of quarters
\n" ); document.write( "---
\n" ); document.write( "5x + 25y = 525
\n" ); document.write( "x = y + 15
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "5x + 25y = 525
\n" ); document.write( "x - y = 15
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
