The value of the unknown that makes the left and right sides of the equation equal is called the solution of the equation. If it is the solution of an unary equation, this solution is also called the root of the equation. The process of solving an equation is called solving an equation.
To solve an unary linear equation, we usually have to go through the steps of denominator removal, bracket removal, term shifting, merging similar terms, and coefficient transformation to 1. One-dimensional linear equations generally have only one root.
I hope it can help you solve the problem.
