Question #N327
If $2x + 3y = 12$ and $x - y = 1$, what is the value of $x$?
A. 2
B. 3
C. 4
D. 5
Correct Answer is: B
To solve for x, we can use elimination. Multiplying the second equation by 3, we get $3x - 3y = 3$. Adding this equation to the first equation, we get $5x = 15$. Dividing both sides by 5, we find that $x = 3$.
