Explanation for Question 1 From the Math (No Calc) Section on the Official Sat Practice Test 8
So we see that in question number one, we're trying to find out what 2 is the value of X. 3 So essentially we're going to take this really long equation that they've given to 4 us and just solve it for X. 5 And the first thing we can notice is that X shows up quite a 6 few times. We also have normal numbers that haven't been simplified, 7 simplified. And so step one is going to be combined like terms, 8 right? And so we start with three X plus X plus X plus X. 9 So that's 3, 4, 5, 6, 10 X's right. So six X. Then if we look at just the normal numbers 11 we have minus three minus two, which is negative five is equal to seven 12 plus X plus X, which is two X. 13 So now we've really simplified this. And our next step is going to be 14 to get all the Xs to one side of the equation and all the 15 normal numbers to the other side of the equation. 16 So to do that, I'm going to first move the two X over to 17 the left side of the equation by subtracting two X. 18 So these here on the right we'll cancel. 19 And then on the left, I'll get four X minus five, 20 and that's seven drops down is equal to seven. 21 So now that I have my X's on the left, I'm going to move 22 my plus for my minus five, by adding five to both sides, 23 these fives will cancel. I'll be left with four X is equal to 12. 24 And the last step here is to divide by four because the four is 25 the last thing that's attached to the X. 26 And I get the X is equal to three. Sorry. 27 Correct? Answer is the.
