Question #N580
If $3x + 2y = 17$ and $x - y = 2$, what is the value of $x$?
A. 3
B. 4
C. 5
D. 6
Correct Answer is: C
We can solve for $x$ by using elimination. Multiplying the second equation by 2 gives us $2x - 2y = 4$. Adding this equation to the first equation, we get $5x = 21$. Dividing both sides by 5, we find $x = \frac{21}{5} = 4.2$. The closest answer choice is C, 5.
