An equation is a statement that two expressions are equal. For example, the expression 5 + 3 is equal to the expression 6 + 2 (because they both equal 8 ), so we can write the following equation: 5 + 3 = 6 + 2. All equations have an equal sign ( = ). The = sign is not an operator like addition ( + ) or subtraction ( − ) symbols.

Equation - Wikipedia
https://en.wikipedia.org/wiki/Equation
Description. An equation is written as two expressions, connected by an equals sign ("="). [2] . The expressions on the two sides of the equals sign are called the "left-hand side" and "right-hand side" of the equation. Very often the right-hand side of an equation is assumed to be zero.

In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign.

Linear Equations - Math is Fun

These are all linear equations: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1. So +1 is also needed. And so: y = 2x + 1. Here are some example values:
