A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and the first power of a single variable. Linear equations can have one or more variables.
Examples:
x = 3
2x - 3y = 17
x/2 - y/3 + z/4 = 1
A linear inequality meets all of the conditions met by a linear equation, except that the equal sign is replaced by an inequality symbol: <, ≤, >, or ≥.
Examples:
x ≤ 3
2x - 3y > 17
x/2 - y/3 + z/4 ≥ 1
