What Is Solution Of Equation

The solution of an equation is the value or set of values that make the equation true. In other words, it is the value or values that satisfy the equation. To find the solution of an equation, we need to isolate the variable or variables on one side of the equation. This can be done using various mathematical operations such as addition, subtraction, multiplication, and division.

Types of Equations

Systems Of Linear Equations Mathbitsnotebook Jr

There are different types of equations, including linear equations, quadratic equations, polynomial equations, and rational equations. Each type of equation has its own unique characteristics and requires different methods to solve.

Linear Equations

A linear equation is an equation in which the highest power of the variable is 1. For example, 2x + 3 = 5 is a linear equation. To solve a linear equation, we can add, subtract, multiply, or divide both sides of the equation by the same value to isolate the variable.

Type of EquationExample
Linear Equation2x + 3 = 5
Quadratic Equationx^2 + 4x + 4 = 0
Polynomial Equationx^3 + 2x^2 - 7x - 12 = 0
Rational Equation(x + 2) / (x - 2) = 3 / 4

To solve an equation, we need to follow a series of steps. First, we need to simplify the equation by combining like terms. Next, we need to isolate the variable by adding, subtracting, multiplying, or dividing both sides of the equation by the same value. Finally, we need to check the solution by plugging it back into the original equation.

Step-by-Step Solution

For example, to solve the equation 2x + 3 = 5, we can follow these steps:

  • Subtract 3 from both sides of the equation: 2x = 5 - 3
  • Simplify the equation: 2x = 2
  • Divide both sides of the equation by 2: x = 2 / 2
  • Simplify the equation: x = 1
