1. Denominator removal: This is the first step to solve a linear equation. The linear equation with denominator must be named first, of course, this step can be omitted if there is no denominator in the equation.

2. Delete the brackets: after deleting the denominator, the brackets should be deleted. If there is a denominator, remove the denominator first and then remove the brackets. Of course, if there is no bracket, this step can be omitted.

3. Moving terminology: This is a very important step. Every unary linear equation has a step, that is, moving the same type of data to the same side, in other words, moving the number to one side of the equal sign and the unknown to the other side of the equal sign. We are used to moving the unknown to the left of the equal sign.

4. Merging similar items: Merging similar items in polynomials into one item is called merging similar items. The coefficients of similar items are added together, and the results are taken as coefficients, and the index of letters remains unchanged. Solving the linear equation of one variable is a crucial step, and it is also a very important step. When merging similar items, we should follow the rules of merging similar items.

5. Turn the unknown coefficient into one: this is the last step of one-dimensional linear equation. As long as the unknown coefficient is changed into 1, the result is the solution of this one-dimensional linear equation, which is the final result we need to get.
