To solve this equation, we will first simplify both sides of the equation:

7х−6х-6х6/4 = 5х+1х+1х+1/3 - 3х+2х+2х+2

To simplify the left side, distribute the 7:
7х−427х - 427х42/4 = 5х+1х+1х+1/3 - 3х+2х+2х+2

Next, simplify the right side by distributing the 5 and 3:
7х−427х - 427х42/4 = 5х+55х + 55х+5/3 - 3х+63х + 63х+6

Now, find a common denominator for the fractions on the right side, which is 12:
7х−427х - 427х42/4 = 4(5х+5)4(5х + 5)4(5х+5)/12 - 3(3х+6)3(3х + 6)3(3х+6)/12

Simplify the fractions on the right side:
7х−427х - 427х42/4 = 20х+2020х + 2020х+20/12 - 9х+189х + 189х+18/12

Combine the fractions on the right side:
7х−427х - 427х42/4 = 20х+9х+20−1820х + 9х + 20 - 1820х+9х+2018/12
7х−427х - 427х42/4 = 29х+229х + 229х+2/12

Now, clear the fractions by multiplying by 12:
127х−427х - 427х42/4 = 1229х+229х + 229х+2/12
37х−427х - 427х42 = 29х + 2

Distribute on the left side:
21x - 126 = 29x + 2

Subtract 21x from both sides:
-126 = 8x + 2

Subtract 2 from both sides:
-128 = 8x

Divide by 8 on both sides:
x = -16

Therefore, the solution to the equation 7х−6х-6х6/4 = 5х+1х+1х+1/3 - 3х+2х+2х+2 is x = -16.
