I have two questions, I understand mostly how coding works but i'm unfamiliar with this language and pretty new to it.

1)How do you get a program to use the solve() function?

2)How would you work the if/then statement in this case.

What the program is doing is just solving 3 equations and giving the 3 answers. I'll either know the variables in the equation, or the numbers that the equation equals and will need to solve for the unknown variables inside the equation.

The error I get is "Error:Argument must be a variable name" and with my if/then statement, if i don't choose "A" then I get "A test did not resolve to TRUE or FALSE"

-Hopefully this is clear….if not I will try to clarify a bit! Thanks!
