Question #N440
If 2x + 3y = 12 and x - y = 4, what is the value of x?
A. 3
B. 4
C. 5
D. 6
Correct Answer is: D
To solve for x, we can use elimination. Multiplying the second equation by 3, we get 3x - 3y = 12. Adding this equation to the first equation, we get 5x = 24. Dividing both sides by 5, we get x = 24/5 = 4.8. Since the only choice that is close to 4.8 is 6, the answer is D.
