Solving Linear Inequalities
An inequality is a sentence with <, >, ≤, or ≥ as its verb.
For any given real numbers x, y, and z. Following are some principles to Solve Inequalities:
Addition Principle for Inequalities : If x < y is true, then x + z < y + z is true.
Multiplication Principle for Inequalities : If x < y and z > 0 are true, then xz < yz is true. If x < y and z < 0 are true, then xz > yz is true.
