Question

Considere os dois números complexos z1 = (5x + 9y) + 12i e z2 = –8 + (15x – 9y)i. Sabendo que z1 = z2, então:

Answer 1

Z1=z2
(5x+9y)+12!=-8+(15x-9y)!
5x+9y+479001600=-8+(15x-9y)!
5x+9y-15x+9y!=-8-479001600
-10x+18y!=-479001608
X=479001608+18y!
-10×(479001608+18y!+18y!=479001608
-4790016080-180y!+180y!=479001608
360y!=479001608+4790016080
360y!=52690176888
y!=52690176888÷360
y!=4791346640
X=479001608+18y!
x=479001608+18×4791346640
X=86244239520
