Explanation for Question 2 From the Math (No Calc) Section on the 2019 May Sat
Question number two says if three times three X was five is equal to 2 two X minus eight. What is the value of X? 3 So to solve this equation to solve for X, 4 we need to add and subtract like terms and then isolate 5 acts on one side. So let's start by doing that. 6 I'm just going to rewrite this equation. 7 Three X three times three X plus five is equal to two X minus 8 H. So the first step is to distribute. 9 So we're going to make this nine X plus 15 is equal to two 10 X minus eight, and then we're going to subtract 11 two extra, both sides and subtract 15 from both sides. 12 So minus two X minus 15, 13 and we get seven X is equal to negative 14 23. Then when we divide by seven, 15 we get X is equal to negative 23 7. 16 And so the answer here is.
