Explanation for Question 16 From the Math (No Calc) Section on the 2019 May Sat
So question 16 says if X, 2 Y is the solution to the given system of equations, 3 what is the value of Y? Now they already told us that X is 4 equal to two. So we have the value of one of the variables. 5 So all we need to do is plug that in and solve for Y. 6 So we're going to plug that into the top equation and do three times 7 two plus Y is equal to 29. 8 That gives us six plus Y is equal to 29, 9 and then we can subtract six from both sides and we get Y is 10 equal to 23. And that's your final answer for question 16.
