To make it easier to determine how many solutions are in the equation, I am going to solve it first.
Distribute 8:
8(x - 3) = 8x - 24
8x - 24 = 8x - 24
And what I see is that the left equals the right. This means that whichever value of x I stick into the equation, the other side will always be equal to that. In equations like this, there are infinite solutions, because every single value of x out there will make the equation true.
