An equation is a mathematical statement that shows the relationship between two or more quantities. It consists of two sides, connected by an equals sign, with expressions or numbers on each side.
The purpose of an equation is to solve for unknown quantities or to describe a mathematical relationship between variables. It is used in various fields of science and in everyday life to model and understand phenomena.
To solve an equation, you must isolate the variable on one side of the equals sign and simplify the other side using mathematical operations. The goal is to end up with the variable equal to a specific value, which can be found by following a series of steps.
There are many types of equations, including linear, quadratic, exponential, logarithmic, and trigonometric equations. Each type has its own unique characteristics and methods for solving.
An equation has an equals sign and shows a relationship between two or more quantities, whereas an expression does not have an equals sign and does not show a relationship. An equation can be solved for a specific value, while an expression cannot.
