how do you solve fo x and y 28+5yi=-7x+40i ?How to solve for x and y using complex numbers?
Match the real and imaginary parts and then solve for x and y.
28 + 5i y = -7x + 40 i
40i = 5i y
8 = y
28 = -7x
x = -4How to solve for x and y using complex numbers?
hint: a+bi = c + di if and only if a = c and b=d (i.e. the real and corresponding imaginary parts are equal)
28 = - 7x
5y = 40
x = - 4 , y = 8
