Given equation :

3x - 7(x + 2) = 6 - x


Step by step explanation :


First, Open the brackets of L. H. S


3x - 7x - 14 = 6 - x


Simplify it further


-4x - 14 = 6 - x


Take coefficients on one side and variables on other side


- 14 -6 = -x + 4x


- 20 = 3x


-20/3 = x


x = -20/3


Hence,


Value of x is -20/3
