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

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

x = - 7, y = 10

Solution steps

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

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

[2 + x = - 5 3 - y = - 7]

[2 + x = - 5 3 - y = - 7] : x = - 7, y = 10

x = - 7, y = 10

(2 - i) (- 3 + 2 i) (5 - 4 i) = 4 x - 3

2 ai - 3 j = a^{2} i + 6 j

7 x + (x - 3 y) i = 3 y + 9 i

\frac{1 + ai}{6 + bi} = 2 + 5 i

3 (5 + 3 bi) + 2 i = 2 a - 7 i
