You can put this solution on YOUR website!
x = dimes
\n" ); document.write( "y = quarters
\n" ); document.write( "---
\n" ); document.write( "y = x + 3
\n" ); document.write( "10x + 25y = 320
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = -3
\n" ); document.write( "10x + 25y = 320
\n" ); document.write( "---
