2x-7 =
you want to isolate x so you need to first
add 7 to both sides
2x - 7 + 7 = + 7
-7 and + 7 cancel each other out so you get
2x = 7
which is the same as
2 * x = 7
to move the 2 over to the other side you have to divide both sides by 2
(2 / 2) * x = (7/2)
2 divided by 2 equals 1 and anything multiplied by 1 equals itself you're left with
x = 7/2
or
x = 3.5
If AC equals 6 and BD equals 4, then AB equals 5.
When equals are added to equals, you don't necessarily get wholes. But whatever you do get, they're equal.

I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
