Question 1127372: Find the values of x and y that make the equation true.
By the way, x and y are variables and i is imaginary number. We have covered complex numbers, imaginary numbers, factoring, square rooting, Quadratic formula and equations, but I still don't know what to do. I was thinking about making it equal to 0 but it isn't standard form. I do not know what the first step that I need to take is, please help?

Then it means that
10x = 5 (1)
and
-4 = 28y, (2)
which implies x = = and y = = .
That's all.
Complex numbers are equal if and only if their real parts are equal AND their imaginary parts are equal, too.
