Answer 1

espero ter ajudado...

Answer 2

a
(x:4).6=54

 x  .   6  =   54
---
 4

 6x    = 54
-----
   4

6x = 4.54
6x = 216
x = 216/6
x = 36

b)
x - 27 = 5
x = 5 + 27
x = 32

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
c)
5 + 2x = 27
2x = 27 - 5
2x = 22
x = 22/2
x = 11

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
d)
x - 3.27 = 2
x - 81 = 2
x = 2 + 81
x = 83


¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
e)
2x = 50 - 16
2x = 34
x = 34/2
x = 17

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
f)
 2x - 35 - 39 = 30
2x - 74 = 30
2x = 30 + 74
2x = 104
x =104/2
x = 52
