An equation is a mathematical statement that asserts the equality of two expressions, typically involving variables, numbers, and mathematical operations (like addition, subtraction, multiplication, and division). It consists of two parts: a left-hand side (LHS) and a right-hand side (RHS), separated by an equals sign (=).
For example:
2
𝑥
3
=
7
2x+3=7
This is an equation where
2
𝑥
3
2x+3 is equal to 7. The goal is often to find the value(s) of the variable(s) (like
𝑥
x) that make the equation true.
