Question

There are three ways to solve a system of equations. Sometimes it is easier to use one method instead of another. Provide an example of three systems and explain what method should be used to solve and why it is the easiest method given the way the system is written.

Answer 1

Answer is graphing, substitution and elimination

Step-by-step explanation

Graphing is easy if you have a graphing app like D e s m o s graphing calculator - where you can plug in the equations and find the point where they intersect.

Substitution works great when the equations are already in y intercept form, substitute one equation into the other for the value of a variable.

Elimination works best when the two equations have one variable that can be eliminated through adding together a same positive and negative variable, such as +2x and -2x
