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

Answer 1

Answer:

The answer is option A.

Step-by-step explanation:

The steps are :

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

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

$(1) - (2)$

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

$2y = 2$

$y = 1$

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

$x + 1 = 8$

$x = 7$
