Which of the following best describes when the elimination method of solving systems of equations is most useful?

A. The elimination method is most useful when adding the equations cancels out both x- and y-variables simultaneously.

B. The elimination method is most useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation.

C. The elimination method is most useful when the answer is zero.

D. The elimination method is most useful when one equation can be substituted into the other.

Choice B. The elimination method is most useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation.

Simultaneous equations could be solve by means of variable elimination or substitution.

However, the elimination technique of solving simultaneous equations is used when one can eliminate one of the variable terms from an equation by adding or subtracting another equation.
