Answer 6

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.

Answer 7

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.

Answer 8

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

Answer 9

Follow so far?

OH okay! Thanks for all the help! Math is not my strong suit at all. ;-;

Answer 11

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

Answer 12

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.
