Question

Determine o valor de x e y,de modo que :
a) (2x-5y)+(x+y)=16+i

Answer 1

Boa noite Stephany

(2x - 5y) + (x + y)i = 16 + i

2x - 5y = 16
 x + y = 1
5x + 5y = 5

7x = 21
x = 3
6 - 5y = 16
5y = 6 - 16 = -10
y = -2

S = (3, -2)

Answer 2

Vamos lá!!!
(2x-5y)=16
(x+y)=1
x=1-y
2(1-y)-5y=16
2-2y-5y=16
2-7y=16
-7y=14
y=-2
então x:
x=1-(-2)
x=3
