Question #N1003
If $3x + 2y = 12$ and $x - 2y = 4$, what is the value of $x$?
A. 2
B. 3
C. 4
D. 6
Correct Answer is: C
To solve for $x$, we can add the two equations together. Notice that the $y$ terms cancel out: $(3x + 2y) + (x - 2y) = 12 + 4$, which simplifies to $4x = 16$. Dividing both sides by 4, we get $x = 4$.
