For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2. Whereas if we speak about linear equation in two variables, it has two solutions. The concept of linear equation in one variable has been covered in this lesson, including its definition, solutions, examples, word problems and worksheet questions. This is an important topic for Class 6, 7 and 8 students. The concepts covered in this lesson are mentioned below in the table of contents. So, what is one variable equation? Linear Equation in One Variable Definition A linear equation in one variable is an equation which has a maximum of one variable of order 1. It is of the form ax + b = 0, where x is the variable. This equation has only one solution. A few examples are: 3x = 1 22x-1=0 4x+9=-11 Standard Form of Linear Equations in One Variable The standard form of linear equations in one variable is represented as: ax + b = 0 Where, ‘a’ and ‘b’ are real numbers. Both ‘a’ and ‘b’ are not equal to zero. Thus, the formula of linear equation in one variable is ax + b = 0. Solving Linear Equations in One Variable For solving an equation having only one variable, the following steps are followed Step 1: Using LCM, clear the fractions if any. Step 2: Simplify both sides of the equation. Step 3: Isolate the variable. Step 4: Verify your answer. Example of Solution of Linear Equation in One Variable Let us understand the concept with the help of an example.For solving equations with variables on both sides, the following steps are followed: Consider the equation: 5x – 9 = -3x + 19 Step 1: Transpose all the variables on one side of the equation. By transpose, we mean to shift the variables from one side of the equation to the other side of the equation. In the method of transposition, the operation on the operand gets reversed. In the equation 5x – 9 = -3x + 19, we transpose -3x from the right-hand side to the left-hand side of the equality, the operation gets reversed upon transposition and the equation becomes: 5x – 9 +3x = 19 ⇒ 8x -9 = 19 Step 2: Similarly transpose all the constant terms on the other side of the equation as below: 8x -9 = 19 ⇒ 8x = 19 + 9 ⇒ 8x = 28 Step 3: Divide the equation with 8 on both sides of the equality. 8x/8 = 28/8 ⇒ x = 28/8 If we substitute x = 28/8 in the equation 5x – 9 = -3x + 19, we will get 9 = 9, thereby satisfying the equality and giving us the required solution.
