\n" ); document.write( "y = 3x - 4
\n" ); document.write( "Use the above equation for substitution, replace y with (3x-4) in the equation below
\n" ); document.write( "-6x + 2y = -8
\n" ); document.write( "-6x + 2(3x-4) = -8
\n" ); document.write( "-6x + 6x - 8 = -8
\n" ); document.write( "Note that we end up
\n" ); document.write( "0x = 0
\n" ); document.write( ":
