You can put this solution on YOUR website!
x = number of etchings sold at $30
\n" ); document.write( "y = number of etchings sold at $55
\n" ); document.write( "---
\n" ); document.write( "x + y = 10
\n" ); document.write( "30x + 55y = 400
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 10
\n" ); document.write( "30x + 55y = 400
\n" ); document.write( "---
