The complex numbers u and v satisfy the equations u + 2v = 2i and iu + v = 3. Solve the equations for u and v, giving both answers in the form x + iy, where x and y are real.
u = -2 - 2i
v = 1 + 2i
u = 2 + 2i
v = 1 - 2i
u = 2i - 2
v = -1 - 2i
u = 1 + 2i
v = - (2 + 2i)
Solve the equation (2 + 3i)x = (4 - 5i) for x.
x = (4 + 5i) / (2 + 3i)
x = (4 - 5i) / (2 - 3i)
x = (4 - 5i) / (2 + 3i)
x = (4 + 5i) / (2 - 3i)
