One-dimensional equation is an important concept in mathematics, which helps us to express unknowns with symbols and solve problems by establishing equations. One-dimensional equation is a mathematical expression that uses letters to represent unknowns. By establishing simple equations, we can solve various practical problems.

1, if we know that the sum of two numbers is 10.

For example, if we know that the sum of two numbers is 10, we can set an unknown as x and then list the equations. There are many forms of simple equations, and the following are several common types: linear equation: this equation represents the linear relationship between one variable and another. Algebraic equation: This equation represents the nonlinear relationship between one variable and another.

2. This equation represents the value of a fraction.

Fractional equation: This equation represents the value of a fraction. For example, 2/3x=4 means that two thirds of x equals 4. There are many solutions to simple equations, and the following are several commonly used methods: substitution method: substituting the value of one unknown into the equation to find the value of another unknown. Elimination method: by eliminating the unknown in the equation, the value of another unknown is obtained.

3. By drawing the function image

Graphic method: Find the intersection point by drawing the function image, and solve the unknown value. Simple equations are widely used in various fields. For example, in physics, we can use simple equations to represent the trajectory of objects; In chemistry, we can use simple equations to express the process of chemical reaction; In engineering, we can use simple equations to express the connection relationship of circuits.

4. The unary equation is one of the important concepts in mathematics.

In a word, the unary equation is one of the important concepts in mathematics, which helps us to express unknowns with symbols and solve problems by establishing equations. By understanding the concept, types, solutions and application fields of unary equation, we can better understand and apply it to solve various practical problems.
