Explanation:
The equation is 
Frida started to solve the equation by adding 3 to both sides.
Thus, the equation becomes,

This will not solve the equation.
To solve the equation
, we need to divide both sides of the equation by 3.
Thus, the equation becomes,

Dividing we get,

Hence, Frida cannot solve the equation by adding 3 to both sides of the equation. To solve the equation, Frida needs to divide both sides of the equation by 3.
Thus, to solve the equation
Frida needs to divide both sides of the equation by 3.

Since we are evaluating, we use PEMDAS so we know the order the operations. Follow PEMDAS:
Original Expression: (-1)8+(-1)7-16-14-(-1)2.
Evaluating: -8-7-16-14+2
-8-7=-15-16=-31-14=-45+2=-43.
The answer is -43 according to PEMDAS.
