Solving Linear Systems Graphically Graphical Method - on graph paperGraphing a system of linear equations is as simple as graphing two straight lines. When the lines are graphed, the solution will be the (x,y) ordered pair where the two lines intersect (cross).Note: Before you begin, rearrange the equations so they will read "y =". This process will make it easier to … [Read more...] about Solving Linear Systems Graphically

Solving Linear Systems Algebraically Using Substitution
Solving Linear Systems Algebraically Using Substitution The substitution method is used to eliminate one of the variables by replacement when solving a system of equations.Think of it as "grabbing" what one variable equals from one equation and "plugging" it into the other equation.Systems of Equations may also be referred to as "simultaneous equations". Let's look at … [Read more...] about Solving Linear Systems Algebraically Using Substitution
Solving Linear Systems Algebraically Using Addition/Subtraction
Solving Linear Systems Algebraically Using Addition/Subtraction Simultaneous equations got you baffled? Relax! You can do it! Think of the adding or subtracting method as temporarily "eliminating" one of the variables to make your life easier.The goal of the elimination method is to create a situation where one set of the variables will cancel each other out when the … [Read more...] about Solving Linear Systems Algebraically Using Addition/Subtraction
