What is equation thinking? How do you use a good equation to solve a problem?

Requires the use of inverse thinking, too many variables.

1, when equations are required.?

2. When reverse thinking is not good, use forward thinking equations to answer.?

3, When there are 2 or more variables, equations are more convenient when answering.

Equations have a variety of forms, such as quadratic equations, quadratic equations, quadratic equations, etc., but also can be formed into a system of equations to solve multiple unknowns.

Solving equations based on

1, shift the terms to change the sign: some of the terms in the equation with the previous sign from one side of the equation to the other, and add to subtract, subtract to add, multiply to divide by, divide to multiply;

2, the basic nature of the equation:

(1) both sides of the equation at the same time add (or subtract) the same number or the same algebraic formula, the resulting results are still Equation. Expressed in letters, if a=b, c is a number or an algebraic formula.

(2) If both sides of an equation are multiplied or divided by the same non-zero number, the result is still an equation. Expressed in letters, if a=b, c is a number or an algebraic formula (not 0).
