Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho)  -114 = -5x -2(4x+18)

-2 . 4x = -8x        +     -2 . 18 = -36        =   -8x-36


Agora soma os números com incógnitas (no caso x)

-114 = - 5x - 8x -36    


Joga a incógnita do outro, tornando positiva

-114 = -13x - 36            

13x -114 = -36


e o 114 do outro lado, ficando positiva também  

13x -114 = -36

13x  = - 36 + 114

13x = 78

x = 78 /13

x= 6


ESPERO TER AJUDADO :)
