Question

Of the methods for solving systems of equations, which is best used when one equation is solved for either x or y, or can easily be solved for x or y?A) SubstitutionB) GraphingC)None of the methods are appropriate for this situation.D) Elimination

Answer 1

The given information is you have one equation that can easily be solved for either x or y, we don't know any information about the second equation.

Then, the most appropiate method is substitution, since you can solve this equation for one of the variables (x or y) and then substitute it in the other equation and solve.

So, the answer is A. Substitution
