Question 1182579
Solve the system by using Elimination Method:
1. 3x² + y² = 21
   4x² - 2y² = -2
<pre>I'm totally convinced that something is MIGHTILY WRONG with the other person who responded.
WHY, after reducing the 2nd equation would you again alter both, when the y<sup>2</sup>s are ELIMINATED IMMEDIATELY, giving one the equation: 5x<sup>2</sup> = 20, which you can then solve EASILY for x?
I'd really love to know what is WRONG with some of these people in this FORUM! Not even KINDERGARTEN or ELEMNTARY students around me make these many MISTAKES. 
Furthermore, many CONFUSE these people who seek help here!!
