Solving a system of three equations involves eliminating one variable to form two systems of two equations. Then solving is the same.Linear Functions. If you studied the writing equations unit, you learned how to write equations given two points and given slope and a point. We are going to use this same skill when working with functions. The only thing different is the function notation. Motorola e5 play
Systems of Equations - a set of two or more equations that use the same variables. System of Linear Equations - when the graph of each equation of a system is a line. Solutions to a System of Equations – a set of values for the variables that makes all the equations true. EXAMPLES EXAMPLE 1: CHECKING SOLUTIONS TO A SYSTEM
