In was just wondering if I got this right.

To determine if your answers are correct, simply substitute the values for the variables into any of the original equations. If they satisfy (make true) the equation,
\n" );
document.write( "then the answers are correct. If you do that here, you'll see that your answers are INCORRECT.
\n" );
document.write( "You should do it like this:
\n" );
document.write( "1)   Factor out GCF, 5 in the 1st equation to get:                  x + y = 1 ------- eq (i)
\n" );
document.write( "2)   Factor out GCF, 3 in the 2nd equation to get: y = - 2x + 4____2x + y = 4 ------- eq (ii)
\n" );
document.write( "3)   Subtract eq (i) from eq (ii) to eliminate y and find the value of x
\n" );
document.write( "4)   Substitute the value of x into any of the 2 original equations to determine the value of y
\n" );
document.write( "5)   Conduct a test as I'd mentioned earlier to determine if your values are correct \n" );
