To solve the equation 4x - 4 = 7x - 7, you can follow these steps:

1. Start by subtracting 4x from both sides of the equation to isolate the variables on one side:

4x - 4x - 4 = 7x - 4x - 7

This simplifies to:

-4 = 3x - 7

2. Now, add 7 to both sides of the equation to isolate the term with "x" on the right side:

-4 + 7 = 3x - 7 + 7

This simplifies to:

3 = 3x

3. Finally, divide both sides by 3 to solve for "x":

3/3 = (3x)/3

This simplifies to:

1 = x

So, the solution to the equation 4x - 4 = 7x - 7 is:

x = 1
