Answer:
Step-by-step explanation:
We have to check each one answer in the following system:
x - 2y = 7
13x + 7y = 8
a. (7,0)
7 - 2.0 = 7 (it's true)
13.7 + 7. 0 = 8 (it's false)
It isn't a correct answer.
b. (5, -1)
5 - 2.(-1) = 7 (correct)
13.5 + 7 (-1) = 8 (wrong)
It isn't a correct answer.
c. (-2,2)
-2 - 2.2 = 7 (wrong)
d. (3, -2)
3 - 2. (-2) = 7 (correct)
13.(3) + 7.(-2) = 8 (wrong)
So, none of them is answer.
