siy=5y+2.1

s i y = 5 y + 2.1

s = 0, y = - 0.42

Solution steps

s i y = 5 y + 2.1

Rewrite

s i y

in standard complex form:

0 + sy i

0 + sy i = 5 y + 2.1

Rewrite

5 y + 2.1

in standard complex form:

(5 y + 2.1) + 0 i

0 + sy i = (5 y + 2.1) + 0 i

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

[0 = 5 y + 2.1 sy = 0]

[0 = 5 y + 2.1 sy = 0] : s = 0, y = - 0.42

s = 0, y = - 0.42

x^{2} + 6 x + 10 = i

5 x - 3 y i = 10 + 12 i

zz + 2 z = 12 + 6 i

9 + (x + 4 y) i = x + 5 i

i (x) = e x^{2} + 2 π
