Question 1131809

Solve the system of equations by the elimination method. (If the system is dependent, let y = c and enter a general solution in terms of c.
{3x−y=14
    4x+3y=−3
(x, y) =
<pre>Don't do this the way the woman did it. It's a very INEFFICIENT way to solve this simple problem.
All you need to do is:
1)  Multiply the 1st equation: (3x - y = 14) by 3 to get eq (iii), or 9x - 3y = 42 
2)  Add eqs (iii) & (ii) to eliminate "y" and get the value of "x."
3)  Substitute the value of x into any of the 2 ORIGINAL equations, and solve to get the value of "y."
That's it. Nothing more, nothing less!!
