Answer:
Infinitely many solutions
Explanation:
This involves distributing and determining what the solution is.
4(x-3) = 4x-12
4x-12 = 4x-12
4x-12+12 = 4x-12+12
4x=4x
Now, since we have that 4x=4x, that is always true, for any number that we use so there are an infinite number of possible values of x, so there are infinitely many solutions.
