Question

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)

Answer 1

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
