Question

Question 13 of 19 Use the elimination method to solve the system of equations. Choose the correct ordered pair x+y=9 x-y=7 O A. (8,1) B. (12,-3) C. (16, -7) D. (7.0) SUBMIT

Answer 1

Answer:

The solution for the system of equations is x = 8, y = 1

Explanation:

Given the pair of equations:

x + y = 9 .....................................................(1)

x - y = 7 ......................................................(2)

To solve by elimintation, add (1) and (2) to eliminate y

2x = 16

x = 16/2 = 8 ............................................(3)

Subtract (2) from (1) to eliminate x

2y = 2

y = 2/2 = 1 ................................................(4)

(3) and (4) form the solution of the equation.

x = 8, y = 1
