Re: Finding real number in complex number
x -3x*i + 2y + 5y*i = 2i
Group real and imaginary parts
(x + 2y) + (-3x + 5y)i = 0 + 2i.
Notice that I added the "0" on the right side.
The real part on the left is x + 2y. We equate that to the real part on the right side = 0
So x + 2y = 0.
Similarly, we equate imaginary parts.
-3x + 5y = 2
Solve the system of equations!
