    As a general rule, what is done to one side is ALWAYS done to the other. When I talk about sides, I'm referring to the sides of the equals sign.

    If I divide one side by (-12.3), I have to divide the other side by (-12.3) Lucky for you, (-12.3) is on both sides.

    What is actually happening is: \[(–6.9) • 9.5 = x • 9.5 • (–12.3)/(-12.3)\]

    We can do the same thing with the 9.5 We will eventually end up with: (-6.9) = x

    The terms don't actually get eliminated, because any number over itself is 1, but multiplying anything by 1 is pointless, so the numbers are essentially eliminated.
