To solve the equation 4x - 4 = -12 + 3x, we first want to get all the variable terms on one side of the equation. We can do this by subtracting 3x from both sides:
4x - 3x - 4 = -12 + 3x - 3x
This simplifies to:
x - 4 = -12
Next, we want to isolate the variable x by adding 4 to both sides:
x - 4 + 4 = -12 + 4
This simplifies to:
x = -8
