This is not a system of equations.
\n" ); document.write( "This is one equation in two forms.
\n" ); document.write( ".
\n" ); document.write( "2x -5y = 10
\n" ); document.write( ".
\n" ); document.write( "Subtract 2x from both sides
\n" ); document.write( ".
\n" ); document.write( "-5y = -2x +10
\n" ); document.write( ".
\n" ); document.write( "Divide both sides by -5
\n" ); document.write( ".
\n" ); document.write( "y = 2/5x -2
\n" ); document.write( ".
\n" ); document.write( "If you want to consider these as two equations, then they line on top of one another.
\n" ); document.write( ".
