Binary linear equation refers to an integral equation with two unknowns and the number of unknowns is 1, which can be reduced to a general formula of ax+by+c=0(a, b≠0) and a standard formula of ax+by=c(a, b≠0), which is applicable to each pair of unknowns of binary linear equation.
Knowledge expansion
Equation is an important mathematical tool, which can help us solve various practical problems. In mathematics, an equation usually refers to an expression containing an unknown number and an equal sign, such as x+2=5. In this expression, x is an unknown number, and the equal sign means that the values on both sides are equal.
Concept of equation
In social sciences, equations can be used to describe social phenomena and human behaviors, such as population growth, crime rate and education level. By using equations, we can better understand and predict social phenomena and human behavior.
In addition, equations also play an important role in computer science and artificial intelligence. For example, in computer science, equations can be used to describe algorithms and data structures to help programmers better understand and implement algorithms. In the field of artificial intelligence, equations can be used to train machine learning models and help machine learning algorithms to learn and predict data better.
It can be traced back to ancient times, but the real development was between16th century and18th century. During this period, mathematicians began to use symbols to represent unknown and known numbers, and began to study how to solve equations.
In modern mathematics, equations are widely used in various fields, including algebra, geometry, physics, chemistry and so on. For example, in algebra, equations can be used to solve various problems, such as solving unknown values, judging whether equations have solutions, solving general solutions of equations and so on. In geometry, equations can be used to describe various shapes and curves, such as straight lines, circles and ellipses.
Besides algebra and geometry, equations are also widely used in physics and chemistry. For example, in physics, equations can be used to describe the laws of motion of objects, electromagnetic fields, gravitational fields and so on. In chemistry, equations can be used to describe the process and results of chemical reactions.
In a word, equation is a very important mathematical tool, which is widely used not only in mathematics, but also in real life. By using equations, we can better understand and solve various practical problems.
