Explanation for Question 1 From the Math (Calc) Section on the 2020 October Sat
So question number one is asking us which value of, 2 and satisfies the equation. In other words, 3 say, you're just asking you what is N solve for N and we see 4 that N has a two attached to it. And the best way to get 5 rid of that too, is going to be to divide by two, 6 because if we divide by two, then the two on the top and the 7 two on the bottom cancel, and we're just left with N which is what 8 we're looking for. And negative 22 divided by two is negative 11. 9 So our best answer is going to be B.
