1. Start with "Xie".

2. If there is a denominator, go to the denominator first.

3. If there are brackets, remove them.

4. Move the project if necessary.

5. Merge similar projects.

6. The coefficient reaches 1 to get an unknown value.

An equation with unknowns is called an equation, or an equation with unknowns is an equation. 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.

Think about solving problems:

1, estimation method: an introductory method when you are just learning to solve equations. Estimate the solution of the equation directly, and then substitute it into the original equation for verification.

2. Apply the properties of the equation to solve the equation.

3. Merge similar terms: transform the equation into a monomial.

4. Move the term: move the unknown term to the left and the constant term to the right.

For example: 3+x= 18

Solution: x= 18-3

X=3

5. Delete brackets: Use the rule of deleting brackets to delete brackets from the equation.

For example: 4x+2(79-x)= 192.

Solution: 4x+ 158-2x= 192.

4x-2x+ 158= 192

2x= 192- 158

X= 17

The value of the unknown that makes the left and right sides of the equation equal is called the solution of the equation. The process of finding all solutions of an equation or judging that an equation has no solution is called solving an equation. An equation is an equation that must contain an unknown equation. An equation is not necessarily an equation, but it must be an equation.

Introduction to equation:

An equation refers to an equation containing unknowns. It is an equation that represents the equal relationship between two mathematical expressions (such as two numbers, functions, quantities and operations), and the value of the unknown quantity that makes the equation hold is called "solution" or "root". The process of finding the solution of the equation is called "solving the equation".

By solving the equation, we can avoid the difficulty of reverse thinking and directly list the equations with the quantity to be solved. There are many forms of equations, such as one-dimensional linear equation, two-dimensional linear equation, one-dimensional quadratic equation and so on. , can also be combined into equations to solve multiple unknowns.

In mathematics, an equation is a statement containing one or more variables. Solving an equation involves determining which variables have values that make the equation valid. Variables are also called unknowns, and the value of the unknowns satisfying the equation is called the solution of the equation.
