How to solve the problem of removing brackets in the equation of one degree?


It depends on the topic, but generally speaking, you need to find the equivalent relation in the topic first, then set the unknown number, list the equation, and then solve the equation. When removing the brackets, you should pay attention to the sign. If the negative sign is before the brackets, when removing the brackets, you should first change the sign, and then multiply the monomials, and finally solve the problem
