Question

28=8x+12-7x

If I have to add 8x and 7x, where would the number be at?

Answer 1

You mean the +12 term?

Answer 2

Keep in mind, you are subtracting 7x's from 8x's. Not adding them :D

Answer 3

is the problem even possible?? sorry, i cant think tight now D:

Answer 4

right*

Answer 5

im just so confused with this

Answer 6

Keep in mind with addition, you can add/subtract in any order you want.

So:
28=8x+12-7x
Is the same thing as:

28=8x-7x+12

So let's deal with the x's first.

If you have 8 of something, and you take 7 of those things away, how many things are left? XD

Answer 7

1 lol

Answer 8

Good, and our "thing" is x :) so let's write it that way, we have 1 x left over

28=8x-7x+12
28=1x+12
28=x+12

Look ok so far? :) now we want to get x alone, hmmmm

Answer 9

-12 from both sides?

Answer 10

Yes good good :)
