Answer: The answer is YES.
Step-by-step explanation: The given system of equations is
![y=2x+6,\\\\y=-3x-14.](https://img.qammunity.org/2020/formulas/mathematics/high-school/8hft2m4mcu17ud4p6rkabeubikf5z350t0.png)
We are to check whether (4, 2) is a solution of the given system or not.
Comparing both the given equations, we have
![2x+6=-3x-14\\\\\Rightarrow 2x+3x=-14-6\\\\\Rightarrow 5x=-20\\\\\Rightarrow x=-4,](https://img.qammunity.org/2020/formulas/mathematics/high-school/7cv86eebasmbccstnm0somlb36v50ef2i3.png)
and
![y=2x+6=2*(-4)+6=-2.](https://img.qammunity.org/2020/formulas/mathematics/high-school/5j2viwyck7562yfmjp9nkge6fuh8yalg21.png)
Therefore, (-4, -2) is a solution of the given system.
Thus, the answer is YES.
