y=-8x-3 x+y=7 Is (3,4) a solution of the system? Choose 1 answer: (A) Yes (B) No

Substitute and Check: First, we will substitute the point (3,4) into the first equation and check if it holds true. The first equation is y = -8x - 3. If we substitute x=3 and y=4, we get 4 = -8*3 - 3. Calculation Result: After performing the calculation, we find that 4 = -24 - 3, which simplifies to 4 = -27. This is not true. Therefore, the point (3,4) does not satisfy the first equation. Point (3,4) Evaluation: Since the point (3,4) does not satisfy the first equation, there is no need to check the second equation. The point (3,4) cannot be a solution to the system if it does not satisfy both equations.
