Simultaneous equations and inequations

Worksheet overview

Description:

Solving equations, simultaneous equations and inequations belongs to the branch of mathematics called Algebra. These equations are often used in the field of science to assist with their most important task: that of solving problems. Throughout the history of mathematics numerous mathematicians have dedicated many years of study to the procedures needed to solve equations and simultaneous equations. In this unit we focus on quadratic or higher degree equations, linear and quadratic simultaneous equations, irrational equations and inequations as well as methods to solve them. This last type of equation is presented within the context of everyday life where they are used to compare offers or budgets etc.
