document.write( "x+y=2 x-y=4 I have tryed to solve it by elimating the variable y after I did that I added the two equations and got 2x=6 then I divided by 2 and I got x=3 for y all I did was put the x value in the equation and then solve but when I put all toghter the answer doesn't equal what the equation says \n" );
