Significance of solving equations:Solving equations eliminates the difficulty of reverse thinking, and can directly list the equations containing the quantities to be solved. Equations come in many forms, such as unary linear equations.
Binary linear equations, unary quadratic equations.
and so on, you can also form a system of equations to solve multiple unknowns.
In mathematics, an equation is a statement that contains an equation of one or more variables. Solving the equation involves determining which values of the variable make the equation true. Variables are also known as unknowns, and the value of the unknowns that satisfies equality is called the solution of the equation.

Solution: 3x=18-6
3x=12x=4
Considerations for solving equations.
1. If there is a denominator, go to the denominator first.
2. If there are parentheses, remove the brackets.
3. If you need to move the item, you will move the item.
4. Merge similar items.
5. The coefficient is reduced to 1 to obtain the value of the unknown.
6. Write "solution" at the beginning.

From the meaning of the question, we can get that this is a unary equation, because the whole is an equation, there is an unknown number x, and the number of unknowns is 1, so we can get a unary equation. From this we can think of several steps to solve the equation, the first step is to shift the term 3x=18-6, the second step is to merge the same terms 3x=12, and the third step is to convert the coefficient to one x=12 3=4, so the solution of the equation x=4, you can check it, and change the position of x to 4, 4 3+6=18, and the equation is still true, so the solution of the equation is correct.

Solution of 3x+6=18: x=4.
The process of solving the equation for 3x+6=18 is as follows:
3x+6=18
3x = 18-6 (shifting the term containing x to one side of the equation and the constant term to the other side of the equation).
3x=12 (combine the bundles and compose the same terms, calculate 18-6) x=4 (divide both sides of the equation by 3 at the same time, solve x).
