Question

a) (x + 4) + 4y = 16+5i
b)-10xi + 5y +3 = 2y-20i ​

Answer 1

Resposta:

a) (x + 4) + 4y = 16+5i

esqueceu o i

==> Se for  (x + 4) + 4yi = 16+5i

x+4=16  ==>x=12

4y=5  ==>y=5/4

==>se for (x+4)i+4y=16+5i

x+4=5 ==>x=1

4y=16 ==>y=4

b)-10xi + 5y +3 = 2y-20i ​

-10x =-20 ==>x=2

5y+3=2y ==>3y=-3 ==>y=-1
