Question

a) 18×-43=65é=
b) 23.×-16=14-17×=a
c) 10y-5-5y-6-20.

Answer 1

18x - 43 = 65
18x = 65 + 43
18x = 108
  x = 108/18
  x = 6
==============================================
23x - 16 = 14 - 17x =
23x + 17x = 14 + 16
40 x = 30
    x = 30/40           simplificando por 10
    x = 3/4
==============================================
10y - 5 - 5y - 6 - 20 =
5y - 31
