You can put this solution on YOUR website!

Don't do this the way the woman did it. It's a very INEFFICIENT way to solve this simple problem.
\n" );
document.write( "All you need to do is:
\n" );
document.write( "1)  Multiply the 1st equation: (3x - y = 14) by 3 to get eq (iii), or 9x - 3y = 42 
\n" );
document.write( "2)  Add eqs (iii) & (ii) to eliminate \"y\" and get the value of \"x.\"
\n" );
document.write( "3)  Substitute the value of x into any of the 2 ORIGINAL equations, and solve to get the value of \"y.\"
\n" );
document.write( "That's it. Nothing more, nothing less!! \n" );
document.write( "

\n" );
