75.33
Step-by-step explanation:
you take 81 then multiple it by 93% (gotten by 100% - 7%) and then you get 75.33
you can also multiple 81 by 7% then subtract 81 - 5.67 and get 75.33

The set is the set of all values of that are solutions to the given equation. So all you need to do is check whether and satisfy the equation.
The equation holds, so both 1 and 2 are solutions, and hence is a subset of the solutions.
-2/3
put 1 in x should be 0
k is -2/3
