Which ordered pair is a solution of the equation? X+7y=17

Answer Choices

A. Only (10,1)

B. Only (-4,3)

C. Both (10,1) and (-4,3)

C.) Both the answers are true

Step-by-step explanation:

Simply plug it in

(10, 1) = 10 + 7 (1) = 17

10 + 7 = 17

17 = 17

So A.) is true, but let's check B.)

-4 + 7 (3) = 17

-4 + 21 = 17

17 = 17

B.) is also true

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.
