Anonymous users2024-02-14The process of finding the solution of an equation:
The value of an unknown that equalizes the left and right sides of the equation is called the solution of the equation. The process of finding the entire solution of an equation or determining that there is no solution to an equation is called solving an equation. An equation that must contain an equation of unknowns is called an equation. A rotten positive equation is not necessarily an equation, an equation must be an equation.
1.An equation containing unknowns is called an equation, and it can also be said that an equation containing unknowns is an equation.
2.The value of the unknown that makes the equation true, called the solution of the equation, or the root of the equation.
3.Solving an equation is the process of finding the values of all the unknowns in the equation.
4.An equation must be an equation, and an equation does not have to be an equation. An equation without unknowns is not an equation.
5.Validation: After the equation is generally solved, it needs to be verified. Verification is to substitute the value of the solved unknown into the original equation to see if the two sides of the equation are equal. If the hunger is equal, then the value obtained is the solution of the equation.
6.Precautions: Write the word "solution", align the equal sign, and test.
