Answer 1

A) x=-19
B) x=-55
C) x=-5/14
D) x=-3
F) x=-27
G) x=-79

Answer 2

Respuesta:

a.

-5x - 18 = 77

-5x = 77 + 18

-5x = 95

x = 95/-5

x = 19

b.

-x + 27 = 82

-x = 82 - 27

x = -55

c.

d.

-8x + 12 = 36

-8x = 36 - 12

-8x = 24

x = 24/-8

x = -3

e.

-x + 45 = 72

x = 72 - 45

x = -27

f.

-x - 13 = 66

x = 66 + 13

x = -79
