I want to ask someone who is good at mathematics how to solve the one-dimensional linear equation and the two-dimensional linear equation, and how to calculate those letters.
One-dimensional linear equation and two-dimensional linear equation are the basic equation types in mathematics, and their solutions are usually based on the basic principles and skills of algebra.

The canonical form of a linear equation with one variable is ax+b = 0, and the solution is x = -b/a (when a≠0).

The canonical form of binary linear equation is ax+by = c, and the solution is x = -c/a and y = -c/b (when a≠0 and b≠0).

These letters (a, b, c, etc. ) are calculated by the given conditions in practical problems or mathematical problems. For example, when solving practical problems, we usually establish these equations according to the description of the problem and common sense, and then solve these equations to find the unknown quantity.

The basic steps for solving linear equations with one variable and linear equations with two variables are as follows:

1. Convert the equation into a standard form.

2. Simplify the equation, such as merging similar terms and moving terms.

3. Solve equations, such as substitution method, elimination method, addition and subtraction elimination method, etc.

For example, for a binary linear equation:

2x + 3y = 10

4x - y = 5

We can use the substitution method to solve it:

First, y = 4x-5 is obtained from the second equation.

Then, substitute this expression into the first equation and get 2x+3(4x-5) = 10.

After simplification, 14x- 15 = 10, and further x = 5/2.

Finally, the value of x is substituted into y = 4x-5, and y = 3 is obtained.

So the solution of this binary linear equation system is x = 5/2 and y = 3.
