4x+(3y+4)i=21+7i

4 x + (3 y + 4) i = 21 + 7 i

x = \frac{21}{4}, y = 1

Solution steps

4 x + (3 y + 4) i = 21 + 7 i

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

[4 x = 21 3 y + 4 = 7]

[4 x = 21 3 y + 4 = 7] : x = \frac{21}{4}, y = 1

x = \frac{21}{4}, y = 1

\frac{z}{1 - z} = 1 - 5 i

\frac{3 - i}{z} = 4 + 2 i

t, a = \frac{v f - v i}{t}

(x + i y)^{2} = 2 i x

∣ z ∣ - 3 z = 1 - 3 i
