Mastering One-Variable Equations (หลักสูตร)

After going through this course, the students will understand:
A linear equation in one variable refers to an equation in which there is only one variable, and the highest power of the variable is 1.
The general form of a linear equation in one variable is:
ax + b = 0
Where “x” is the variable.
“a” is the coefficient of the variable x and is not equal to zero.
“ b” is a constant.
The goal when solving linear equation with one variable is to find the value of “x” that makes the equation true.
You can solve these equations by isolating the variable “x” on one side of the equation.
Examples of linear equation with one variable: 2x + 3 = 0 x-5 =0
Linear equations in one variable are used in many different areas of mathematics, including: Algebra, Geometry, Calculus and Statistics.
Linear equations are also used in many real-world applications, such as finding the slope of a line, determine the cost of producing a certain number of items, or determine the cost of purchasing a certain number of items.
The word "linear" in a linear equation refers to the fact that the graph of the equation is a straight line.
