Question #N762
If $3x - 2y = 12$ and $x + y = 4$, what is the value of $x$?
A. 2
B. 4
C. 6
D. 8
Correct Answer is: B
We can use the elimination method to solve for x. Multiplying the second equation by 2 gives us $2x + 2y = 8$. Adding this equation to the first equation gives us $5x = 20$. Dividing both sides by 5 gives us $x = 4$.
