What are the conditions for a linear equation with one variable to have no solution?

One-dimensional linear equation has no solution if:

For the unary linear equation AX+C = 0: when A = 0 and C = 0, the equation has countless solutions; When a = 0 and c≠0, the equation has no solution.

Steps to solve the equation:

1, denominator first.

2. If there are brackets, remove them.

3. Move the project if necessary.

4. Merge similar projects.

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

6. Write "solution" at the beginning.

The meaning of one-dimensional linear equation;

One-dimensional linear equation can solve most engineering problems, travel problems, distribution problems, profit and loss problem, integral table problems, telephone billing problems and digital problems. If only arithmetic is used, some problems may be extremely complicated and difficult to understand.

The establishment of linear equation model will be able to find the equivalence relationship from practical problems and abstract it into a mathematical problem that can be solved by linear equations.
