Dan is going to rent a truck for one day. There are two companies he can choose from, and they have the following Company A charges $92 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.90 for every mile dwen.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.

In order to investigate situations such as that of the skateboard manufacturer, we need to recognize that we are dealing with more than one variable and likely more than one equation. A system of linear equations consists of two or more linear equations made up of two or more variables such that all equations in the system are considered simultaneously. To find the unique solution to a system of linear equations, we must find a numerical value for each variable in the system that will satisfy all equations in the system at the same time. Some linear systems may not have a solution and others may have an infinite number of solutions. In order for a linear system to have a unique solution, there must be at least as many equations as there are variables. Even so, this does not guarantee a unique solution.

In this section, we will look at systems of linear
