(1) denominator: Multiply the least common multiple of each denominator on both sides of the equation.

(2) bracket removal: first remove the bracket, then remove the bracket, and finally remove the braces.

(3) Shift the term: move all the terms containing unknowns to one side of the equation, and other terms to the other side of the equation.

(4) merging similar terms: transforming the equation into the form of ax=b(a≠0).

(5) The coefficient becomes 1.

Equations with unknowns are called equations, or equations with unknowns are called equations.

The value of the unknown quantity that makes the equation hold is called the solution or the root of the equation.

Solving an equation is the process of finding the values of all the unknowns in the equation.

An equation must be an equation, and an equation is not necessarily an equation. An equation without unknowns is not an equation.
