Answer: No

Explanation:

Plug x and y into y=-8x-3 and calculate:

4 = -24 - 3

4 ≠ 27

Therefore (3,4) is not a solution of the system of equations.

Answer:

No

Explanation:

The given point does not satisfy the first equation.

y = -8(3) -3 = -27

4 ≠ -27 . . . . . the first equation is not satisfied.
