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
