You can put this solution on YOUR website!
2x - y = 8
\n" ); document.write( "7x - 3y = 28
\n" ); document.write( "---
\n" ); document.write( "2x - y = 8
\n" ); document.write( "2x - 8 = y
\n" ); document.write( "---
\n" ); document.write( "7x - 3y = 28
\n" ); document.write( "7x - 3(2x - 8) = 28
\n" ); document.write( "7x - 6x + 24 = 28
\n" ); document.write( "---
\n" ); document.write( "x = 4
\n" ); document.write( "y = 0
