Can you solve these in calc with variables? like X

[@OnePunchMath]

No, since these calculators are not capable of symbolic manipulation. You would need a CAS calculator, like the TI-89 Titanium.

I mean who use complex numbers anyway ? It was just intended to solve certain problems in electricity, but it's no use in the real world !
