Answer:
Simplification is a method for solving a system of equations
Explanation:
-Graphing is a real way to solve a System of Equations
-Substitution is a real way to Solve Systems of Equations
-Elimination is a real way to solve Systems of Equations
so, Simplifcation can't be one
Take 2x-4y=6 and 4x+2y=17 for example.
They are both in standard form, so you could change them to y=mx+b and graph it. The intersection is the correct answer.
You can also solve one of the equations for y or x, and substitute that into the other equation, and solve for both x and y
or, you could add the two equations together and solve for x and y.
You can't simplify them.
