Question

Compare and contrast solving a system of three equations to solving a system of two equations.

Answer 1

Comparations:

• You are still solving for variables in both systems of equations,
• You can still use the substitution and elimination method for both systems to solve for the variables.

Contrasts:

• With a system of three equations, you are solving for 3 variables, whereas a system of two equations you are solving for 2 variables.
• While both are a similar process, solving a system of three equations is much lengthier process because you are solving for more variables.
