3=31​ (10x−12)

The equation you've given seems to have a formatting issue. However, if you're asking to solve the equation 3 = 31 / (10x - 12), here are the steps:

1. First, we need to isolate the term with the variable x. We can do this by multiplying both sides of the equation by (10x - 12). This gives us:

   3(10x - 12) = 31

2. Distribute the 3 on the left side of the equation:

   30x - 36 = 31

3. Add 36 to both sides to isolate the term with x:

   30x = 67

4. Finally, divide both sides by 30 to solve for x:

   x = 67 / 30

So, the solution to the equation is x = 67 / 30.
