It seems like there might be a small mistake in the equation you provided, as it presents multiple equal signs. However, I can interpret it as two separate equations:

1. \( 2x - 7 = 12 \)
2. \( 12x - 7 = 1 \)

Let's solve each equation step by step.

### Solving \( 2x - 7 = 12 \):

1. Add 7 to both sides:
\[
2x = 12 + 7
\]
\[
2x = 19
\]

2. Divide both sides by 2:
\[
x = \frac{19}{2} \quad \text{or} \quad x = 9.5
\]

### Solving \( 12x - 7 = 1 \):

1. Add 7 to both sides:
\[
12x = 1 + 7
\]
\[
12x = 8
\]

2. Divide both sides by 12:
\[
x = \frac{8}{12} \quad \text{or} \quad x = \frac{2}{3}
\]

### Summary of Solutions:
- For the equation \( 2x - 7 = 12 \), the solution is \( x = 9.5 \).
- For the equation \( 12x - 7 = 1 \), the solution is \( x = \frac{2}{3} \).
