B) 9 - 4x = 7x- 68

C) 2x/9 - x = 8 + 5x

D) 5 - 4x/3 = -10x/6 - 1/9

Answer 1

A)92
b)-476
C)13
D)/41 Espero te ajundado

Answer 2

A) 2x-8= -76
2x=-68
x=34

b)9-4x=7x-68(-1)
11x=59
x=5.36

c) 2x/9 -x= 8+5x
2x-9x=72 +45x
52x=72
x= -18/13

d) 5-4x/3 = -10x -1/9
(90-6x=-30x-2)/18
36x= -92
x= (92/36)/4
x=23/9
