Question #N67
If $3x + 2y = 17$ and $x - y = 1$, what is the value of $x$?
A. 3
B. 4
C. 5
D. 6
Correct Answer is: C
To solve for $x$, we can use elimination. Multiplying the second equation by 2, we get $2x - 2y = 2$. Adding this equation to the first equation, we get $5x = 19$. Dividing both sides by 5, we get $x = \frac{19}{5}$ or 3.8. Since the question asks for the value of $x$, and only 5 is given as a choice, the answer is 5.
