Answer:

B) Since (-3,-2) does not satisfy both equations, it is not a solution to the

system.

Step-by-step explanation:

The given system of equations is:

{x}^{2}  +  {y}^{2}   + x - 10y - 3 = 0

x + y =  - 4

If (-3,-2) is a solution, then it must satisfy both equations:

Let us substitute into the first equation to get:

{( - 3)}^{2}  +  {( - 2)}^{2}   + ( - 3) - 10( - 2) - 3 = 0

Evaluate the exponents;

9 +  4   - 3  + 20- 3 = 0

27 = 0

This is not true

Also when we substitute into the scond equation, we get;

- 3 +  - 2 =  - 4 \\  - 5 =  - 4

This is also false.

Therefore the point is not a solution.
