Question #N216
If $3x + 2y = 12$ and $x - 2y = 4$, what is the value of $x$?
A. 2
B. 4
C. 6
D. 8
Correct Answer is: C
To solve for *x*, we can add the two equations together. Notice that the *y* terms cancel out. This gives us $3x + 2y + (x - 2y) = 12 + 4$, or $4x = 16$. Dividing both sides by 4, we get $x = 4$.
