Explanation for Question 1 From the Math (Calc) Section on the Official Sat Practice Test 9
Question one asks us what value of X satisfies the equation. 2 Three X plus three is equal to 27. 3 So we just need to solve for the value of X. 4 So we've got three X plus three is equal to 27. 5 Let's start by subtracting three from each side. 6 If you've got three X plus three, minus three is equal to 27 minus 7 three, we have three X is equal to 24 and 8 then dividing both sides by three. We get that X is equal to eight. 9 So you can think B as our answer choices.
