Hi all,
First post here. I have started doing some MGMAT prep and I am having some questions about certain data sufficiency questions. When I am given 2 formulas with 2 variables, sometimes I find that I actually have to actually solve for the variables to know that the variables actually result in different numbers (if I solve for x the answer would be different for solving for y - the answer would be E, neither works).
I know data sufficiency is just understanding if I have enough data, but it seems like these type of questions I actually have to solve for them. How should I tackle these situations? If I solve for everything in every data sufficiency problems I feel like it would be a huge waste of my time, but obviously I want to make sure they are correct. Any advice? Thanks for any insights in advance!

DS look for one of two things:
1) Y/N answer
2) A number or defined solution
You should start with that regardless of the type of DS problem. If it's (1) then you usually don't need to arrive at the solution. Maybe if you share a specific example it would be easier to say

Hi steve.yang24,
Data Sufficiency is a question type that is unique to the GMAT, so most Test Takers need time to learn the proper Tactics and 'get used to' the logic of these questions.
Certain DS questions will require that you do a certain amount of math, but many of those same questions are based on patterns. Your ability to spot those patterns will save you some time and help you to avoid doing too much math. You might also have to train more with Tactical approaches so that you can avoid an 'all math, all the time' approach to DS (and the Quant section overall).
1) How long have you been studying?
2) What materials have you been using (and what specifically for DS?)?
3) What is your goal score?
4) When are you planning to take the GMAT?
