1, denominator, this is the first step to solve a linear equation. Linear equations with denominator must be named first. Of course, this step is omitted if there is no denominator in the equation.

2. Remove the bracket. After removing the denominator, the brackets should also be removed. If there is a denominator, remove the denominator first and then remove the brackets. If there are no brackets, you can omit this step.

3. Mobile terminology. One step of each unary linear equation is to move the data of similar terms to the same side of the equal sign and the unknown to the left side of the equal sign.

4. Find the unknown value directly according to the relationship between the known number and the obtained number in the four operations.

5. Take the term containing the unknown X as a number, and gradually find the value of the unknown.

6. Through calculation, the original equation is simplified first, and then the solution of the equation is obtained step by step.
