Question

Resolva as equaçoes.
a)x + 8 = 0,sendo U =Z
b)x - 8 = 02,sendoU = Q
c) 3x + 18 = x,sendo U = Z
d) 10x + 18 = x,sendo U =N
e)35 - y =4y,sendo U =Z
f)27 - 3y = -3,sendo U = Q
g)200 -3y = -100,sendo U = N
h)11 - 6y = -55 - 12y,sendo U =Z

Answer 1

a) X+8 = 0  ⇒ x = -8

b) X - 8 = 2  ⇒ X= -2/8 ⇒ X= -1/4

c) 3X +18=0 ⇒ X= -18/3 ⇒ X= -6
