Math is like a bag of tricks.

With math, you cannot afford not to understand part of a trick. If you have doubts, go one step back, if necessary all the way to your basic addition, subtraction, multiplication rules.
Know your algebra tricks, such as:

- sign inverts when you move a term to the other side of the equals sign.
- dividing numerator and denominator by the same number is allowed
- how to handle variables with or without exponents in multiplications and additions

Go back to solid ground if you are in doubt. Then, ask the right questions to take the next baby step. Many folks don't ask questions on Brainly, they're asking someone to do their homework. I know you are not like that.
