Pre Calc 11 – Blog #11

This week we learnt about systems of equations. A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system. The equations in the system can be linear or non-linear.

First step: Factor out the equation

Second step: Find the zeros

Last step: Test the numbers to see if your equation is true
