Answer 2

What steps did you execute to come up with B as a possible result?

Answer 3

I just worked out each equation and tested all its solutions.

Answer 4

Yes, but we can't assume that -4/3 is the only solution for each choice. . If you do that then You won't know which choices have more than one solution.

Answer 5

I mean, I worked out each equation and got the answers and tested each solution for each answer to see if it was true.

Answer 6

Here is some insight into how you can approach these.

Answer 7

So we know the first option has two solutions .

Answer 8

This is just for homework not even a grade, I just need to confirm my answer so I know i'm doing it right, I know how to solve these. Please, did I get it right or wrong? You really aren't helping right now -.-
