Answer:
C. Both (10,1) and (-4,3)
Step-by-step explanation:
The equation is x + 7y = 17
Option A: x = 10, y = 1
Now, putting the value in the equation,
L.H.S.,
x + 7y
= 10 + 7*1
= 10 + 7
= 17
Therefore, L.H.S. = R.H.S.
The equation is correct.
Option B: x = -4, y = 3
Now, putting the value in the equation,
L.H.S.,
x + 7y
= -4 + 7*3
= -4 + 21
= 17
Therefore, L.H.S. = R.H.S.
The equation is also correct with this value.
As the option "A" and Option "B" shows the correct value, the answer is both A and B.
