To solve this equation, we first need to distribute the 2/3 to the terms in the parentheses on the left side of the equation:

2/3 (6x - 3) = 8 - (5x + 1)

This becomes:

(4x - 2) = 8 - (5x + 1)

Next, we need to simplify the right side of the equation by first removing the parentheses:

4x - 2 = 8 - 5x - 1

This becomes:

4x - 2 = 7 - 5x

Now, we can combine like terms by adding 5x to both sides of the equation:

4x + 5x - 2 = 7

This becomes:

9x - 2 = 7

Next, we add 2 to both sides of the equation:

9x = 9

Finally, we divide both sides by 9 to solve for x:

x = 1

Therefore, the solution to the equation is x = 1.
