# Solve for y problems

SOLVING EQUATIONS This sections illustrates the process of solving equations of various forms. I suggest that you answer the question in three parts and give them in the following order. Therefore it is unavoidable Asking Questions where you risk falling into XY The best thing you can do about the XY problem is to guard against it when asking questions.

Variables Any lowercase letter may be used as a variable. I argue this because the design process for all software is based on a starting set of requirements “A”. For instance, it is common that you are given problems of this type: You don’t know what you don’t know. Not without simply throwing your program requirements at SO and asking them to do your design for you not recommended.

Division, Square Root, Radicals, Fractions The above features are not supported. At Wyzant, connect with algebra tutors and math tutors nearby. It also shows you how to check your answer three different ways: If you say “That’s going to be really hard. I like to see the hole as the difference , because the triangles are similar and have near-same area, but not exactly same area, so you can construct the hole from the little strip of the geometric difference.

Still ask the same question but give as much pertinent information as possible: When you divide by -1, it will change the signs for all. Wyzant Resources features blogs, videos, lessons, and more about Algebra and over other subjects. Too often I see responses comments asking “why do you need that?

Simply giving part 3 risks appearing to have not read the question. Tutoring Looking for someone to help you with algebra? Answer the OP’s question.

Even though the OP probably needs something else, never neglect to answer the question they have actually asked first and not the question you think they want answered.

So the major problem with the XY problem is that Y is not possible, but you don’t know how much of your design to unwind to get back to the X which is possible. Giving this answer also avoids embarrassment when you think the OP has an XY problem when in fact they don’t. Giving Answers to XY problems In my opinion the biggest problem with XY questions is the frequently unhelpful answers they provoke.

That’s fine because you’ve answered their question and they may well come back with question X themselves. From there you say “I can achieve B if I do D and E and I can achieve C if I do F and G”. All you’ve done is give a little extra information. You’ve met the OP on their terms and answered their question. Parentheses and Brackets Parentheses and brackets [ ] may be used to group terms as in a standard equation or expression.
