Question

50+(3x-4)=2(3x-4)+26 ?

Answer 1

50 + (3x - 4) = 2 (3x - 4) + 26 

50 + 3x - 4 = 6x - 8 + 26

46 + 3x = 6x + 18

28 = 3x

x = 28/3

Espero ter ajudado!

Answer 2

50+(3x-4)=2(3x-4)+26
50+3x-4=6x-8+26
3x-6x=-8+26-50+4
-3x=-8-24+4
-3x=-8-20
-3x=-28
x=-28/-3
x=28/3

confere
50+(3.28/3-4)=2(3.28/3-4)+26
50+(28-4)=2(28-4)+26
50+28-4=56-8+26
50+28-4=56-8+26
78-4=82-8
74=74 correto

resposta: x=28/3
