Question

z+8=8i find the solution set

Answer 1

z = -8+8i

Answer 2

I'm not sure exactly what you are looking for, I guess, if this is not it.

Answer 3

The solution to an equation is usually found by setting it equal to 0, but that would give you 0 = 8i - 8 - z, and that doesn't do much good at all, I don't expect. You can't factor it...

Answer 4

It seems that equation has 2 unknowns.
When you are solving for 2 unknowns, you must have 2 equations.
