##x - 3x = -2x##, not ##2x##.
There could be several reasons for this. It could be a simple calculation error, or you may have used the wrong formula or method. Double check your work and try again. If you are still getting a different answer, seek help from a teacher or tutor to identify the mistake.
2.This could be due to a sign error. Make sure you are using the correct signs (+ or -) throughout your calculations. Also, check the given problem to see if it specifies that the answer should be positive or negative. If you are still unsure, seek help from a teacher or tutor.
3.Algebra can be challenging, and some problems may require multiple steps and a good understanding of the concepts. If you are struggling, review the basics and try to break the problem down into smaller, more manageable steps. Practice and seeking help from a teacher or tutor can also improve your understanding and problem-solving skills.
4.In algebra, letters are used to represent unknown quantities or variables. This allows us to solve for the unknown value using equations and formulas. It is important to understand the meaning of each letter and how it relates to the problem.
5.It depends on the problem. Some simple algebra problems can be solved using basic arithmetic, but for more complex problems, algebra is necessary. It is a valuable tool that can be applied to various real-life situations, so it is important to practice and improve your algebra skills.
