20-12i=5l+(4m)i

20 - 12 i = 5 l + (4 m) i

l = 4, m = - 3

Solution steps

20 - 12 i = 5 l + (4 m) i

Rewrite

5 l + (4 m) i

in standard complex form:

5 l + 4 mi

20 - 12 i = 5 l + 4 mi

Complex numbers can be equal only if their real and imaginary parts are equalRewrite as system of equations:

[20 = 5 l - 12 = 4 m]

[20 = 5 l - 12 = 4 m] : l = 4, m = - 3

l = 4, m = - 3

x^{2} - 4 x i + 5 = 0

2 z^{2} - 5 i z - 2 z = 0

(2 x + y) + (3 i - 5 x i) = 1 - 7 i

0.005 x i = \frac{1}{0.000018 x i}

z^{2} - (3 + 6 i) z - 4 - 6 i = 0
