Question #N291
If 3x - 2y = 10 and 2x + y = 7, 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 2, we get 4x + 2y = 14. Adding this equation to the first equation (3x - 2y = 10), we eliminate y: 7x = 24. Dividing both sides by 7, we get x = 24/7, or x = 3.
