A
解析
The correct answer is A. To solve this system of equations, first multiply the bottom equation by -2 to get -2x+8y=26. Next, add the two equations together(note: their x-values will conveniently cancel out).
2x+3y=18
-2x+8y=26
11y=44
Dividing both sides of the equation 11y=44 yields y=4. Using the original equation x-4y=-13, substitute 4 for y. Thus x-4(4)=-13, or x-16=-13. Adding 16 to both sides results in x=3. Therefore, Quantity A, x+y, equals 3+4, or 7. Quantity B is 6, which is less than 7.
