The key contents of binary linear equations in seventh grade mathematics

An equation with 1, two unknowns and all unknowns of degree 1 is called binary linear equations.

2. An equation group consisting of two linear equations with two unknowns is called a binary linear equation group.

3. The common * * * solution of two equations in binary linear equations is called the solution of binary linear equations.

4. Substitution elimination method: the unknown number of one equation in the binary linear equations is expressed by a formula containing another unknown number, and then it is brought into another equation to realize elimination, and then the solution of the binary linear equations is obtained. This method is called substitution elimination method, or substitution method for short.

5. Addition and subtraction elimination method: when the coefficients of unknowns of two equations in an equation are equal or opposite, the two sides of the two equations are added or subtracted to eliminate them, so that the binary linear equation is transformed into a univariate linear equation, and finally the solution of the equation is obtained. This method of solving equations is called addition, subtraction and elimination, or addition and subtraction for short.

6. The general steps of solving application problems of binary linear equations can be summarized as? Examine, find, list, explain and answer? Five steps, namely:

(1) examination: through the examination of questions, the actual problems are abstracted into mathematical problems, and the known numbers and unknowns are analyzed, two of which are represented by letters;

(2) fin: finding two equation that can express that meaning of the problem;

(3) Column: According to these two equal relations, the necessary algebraic expressions are listed, thus the equations are listed;

(4) solving: solving this set of equations to obtain the values of two unknowns;

(5) Answer: Write the answer on the basis of judging whether the solution of the equation is reasonable.
