Using elimination solve 4x-y=4 and 7x-3y=-3
\n" ); document.write( "-------------------
\n" ); document.write( "4x-y = 4
\n" ); document.write( "7x-3y = -3
\n" ); document.write( "---------
\n" ); document.write( "28x - 7y = 7*4
\n" ); document.write( "28x - 12y = 4*-3
\n" ); document.write( "-------------------------
\n" ); document.write( "Subtract and solve for \"y\"::
\n" ); document.write( "5y = 40
\n" ); document.write( "y = 8
\n" ); document.write( "----
\n" ); document.write( "Solve for \"x\"::
\n" ); document.write( "4x-y = 4
\n" ); document.write( "4x -8 = 4
\n" ); document.write( "4x = 12
\n" ); document.write( "x = 3
