Use the elimination method to solve the system of equations. Choose the correct ordered pair. 5x - 2y = 9 3x + 4y = - 5 O A. (5,
- 5) O B. (1, - 2) OC. (7, 13) D. (3, 3)
1 answer:
Answer:
Step-by-step explanation:
4(5x-2y=9)
-2(3x+4y=-5)
20-20x-8y=36
+6x-6x-8y=10
36-20x=10+6x-6x
36-36-20x-6x=10
-26x=10-36
-26x/-26=-26/-26
x=1
