What is the value of the x variable in the solution to the following system of equations?

Mathematics
1 answer:
defon3 years ago
7 0

ANSWER

The correct answer is C x=3.



<u>EXPLANATION</u>


We have

4x+2y=12---(1)


and


x-y=3---(2).


We solve the two equation simultaneously by elimination method. We need to be smart and eliminate y, since we are looking for x.



We first multiply equation (2) by 2

2x-2y=6---(3).


We add equation (3) and (1).


\Rightarrow 6x=18.

Dividing through by 6 gives

x=3.
