Question

1-Resolva as equações a seguir:
A)18x-43=65
B)23x - 16 = 14 - 17x

Answer 1

A)18x-43=65 
18x = 65 + 43
18x =  108
x = 108/18
x = 6

B)23x - 16 = 14 - 17x
23x + 17x = 14 + 16
40x = 30
x = 30/40
x = 3/4

Answer 2

 18x - 43 = 65

18x = 65 + 43

18x = 108

x = 108
   ---------
      18

x = 6


23x - 16 = 14 - 17x

23x + 17x = 14 +16

40x = 30

x =30
   --------
     40

x = 0,75
