Solving real-world problems using linear systems simultaneous equations can help us solve many real-world problems we may be considering a purchase—for example, trying to decide whether it's cheaper to buy an item online where you pay shipping or at the store where you do not. He linear equations in two variables studied in chapter 1 are readily extended to the case involving more than two variables for example, a linear equation in three variables represents a plane in three-dimensional space in this chapter, we see how some real-world problems can be formulated in terms of systems of linear equations, and we also develop two methods for solving these equations. Linear equations definition: linear equation--an equation between two variables that gives a straight line when plotted on a graph, or a mathematical expression that has an equal sign and linear expression.
