You can put this solution on YOUR website!
x = number of 10 cent stamps
\n" ); document.write( "y = number of 18 cent stamps
\n" ); document.write( "---
\n" ); document.write( "x + y = 45
\n" ); document.write( "10x + 18y = 666
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 45
\n" ); document.write( "10x + 18y = 666
\n" ); document.write( "---
