Algebra Math Help

Can anyone help me with this math communications question?

State some algebraic expressions that are a vector quantity, a scalar quantity and a meaningless quantity, provide a reason.

Hi, a vector is an element of a vector space V. If we take for example V = |R^3, a vector could be v = (1, 2, 3) = i + 2j + 3k, where i, j and k are the standard base of |R^3. A scalar quantity is simply a number, you can take every element of |R, for example sqrt(3) or 5. And a meaningless expression could be 0^(-1), since 0 has no inverse in |R.
I hope this helped you…Bye!

Solving with variables on both sides
