Which is the best method for solving this system of equations?

• Substitution

• Equal Values

• Elimination

For equations below, which method is easier to use? Why?

• Graphing, because both are already in y = mx + b form.

• Substitution, because one equation is already solved for y. 

• Elimination, because both are already in ax + by = c form. 

• None.
