Answer:

B. (1, 4)

Step-by-step explanation:

2x + 3y = 14

5x - 4y = -11

Multiply the first equation by -5 and the second by 2:

-10x - 15y = -70

10x - 8y = -22       Add these 2 equations:

0   - 23y = -92

y = -92/-23 = 4

Now substitute y = 4 in the first equation:

2x + 3*4 = 14

2x = 14 - 12

2x = 2

x = 1.
