Will give best answers!!Use the elimination method to solve the system of equations. Choose the correct ordere

4x + 5y = 51
4x - 5y = 21

A. (4, -1)
B. (9, 3)
C. (9, 4)
D. (4, -5)

Add the two equations to get:
8x = 72

Divide both sides by 8:
x = 9

Plug 9 back into either equation for x, I chose the first:
9*4 + 5y = 51
36 + 5y = 51
5y = 15
y = 3

Ordered pairs are written as (x,y) so the answer is (9,3)

B

B: X-9 ,Y-3
