Explanation for Question 6 From the Math (No Calc) Section on the 2018 March Sat
Question six asks what value of X satisfies the equation above. 2 So I'm just going to start by rewriting this equation. 3 One fourth ax plus negative two is equal to 4 three plus negative X. 5 Now I'm just going to move the excess to the left side of the 6 equation and the Constance to the right side of the equation. 7 So I'm going to add two to both sides and I'm going to add 8 X to both sides. And that gives me five over four acts 9 is equal to five, 10 and then I'm going to divide both sides by five over four. 11 And that gives me X is equal to five times four, 12 over five, which is just equal to four. 13 And so I know that X equals four and the correct answer is answer.
