Question

Use the elimination method to solve the system of equations. Choose the

correct ordered pair.
X+ y = 8
x- y = 6
A. (7,1)
B. (8,2)
C. (9,3)
D. (60)

Answer 1

The answer is option A.

Explanation:

The steps are :

`x + y = 8 - - - (1)`

`x - y = 6 - - - (2)`

`(1) - (2)`

`x + y - x - ( - y) = 8 - 6`

`2y = 2`

`y = 1`

`substitute \: y = 1 \: into \: (1)`

`x + 1 = 8`

`x = 7`
