Olá, boa noite


Temos que:

\frac{1}{2} - \frac{2(x-2)}{3}= 2(3x-4)+26\\ \\\frac{1}{2} - \frac{2x-4}{3} = 6x-8+26\\\\\frac{1}{2} - \frac{2x-4}{3} = 6x+18\\\\(\times 6) \frac{1}{2} - (\times 6) \frac{2x-4}{3} = (\times 6) 6x + (\times 6) 18\\\\3 - 2(2x-4) = 36x + 108\\\\3 - 4x + 8 = 36x +108\\\\11 - 4x = 36x +108\\\\-4x -36x = 108-11\\\\-40x = 97\\\\x = - \frac{97}{40}


Espero ter ajudado, abraços!
