Question

Jim is trying to solve the system of equations. He begins by multiplying equation (1) by D and equation (2) by A. Before he can continue, his friend Angela comes by and says, "No, you should have multiplied equation (1) by E and equation (2) by B. You're going to get the wrong answer."

Is Angela right? Why or why not?

Answer 1

A)
Yes; Jim's way will make both variables disappear, resulting in no solution.



B)
No; Jim is using elimination, Angela is using substitution. Both ways will work.
Eliminate


C)
No; Jim is trying to eliminate x, while she is trying to eliminate y. Both ways will work.



D)
Yes; Jim should have multiplied both equations by the same number. Now his answer will be wrong.
