Answer: If a solution results in zero when subsitituted into the denominator of the equation, the solution is extraneous.
This is because you obtained the solution from a simplified version of the original equation, but you have to check if the solution obtained is a real solution of the original equation
In the case that when you substitute the solution in the original version the denominator becomes zero, this solution must be rejected, because the division by zero is not defined.
Answer:
B.) is the best deal
Step-by-step explanation:
A.) three six packs is $3 for each pack minus $2
