1/3*12/x-8=-1

Sure, let's solve the equation step by step:

1. First, let's simplify the equation. We can multiply 1/3 by 12 to get 4. So, the equation becomes 4/x - 8 = -1.

2. Next, let's isolate the term with x. We can add 8 to both sides of the equation to get 4/x = -1 + 8, which simplifies to 4/x = 7.

3. To solve for x, we can multiply both sides of the equation by x to get 4 = 7x.

4. Finally, we can divide both sides of the equation by 7 to solve for x. So, x = 4/7.
