Question #N72
If $2x+3y=17$ and $x-y=2$, 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 3, we get 3x - 3y = 6. Adding this equation to the first equation, we get 5x = 23. Dividing both sides by 5, we get x = 23/5. Since x = 4.6, and of the choices, only 5 is close to 4.6, the answer is C.
