8x - 11 = 2x + 1 (Subtract 2x from each side and add 11 to each side)
6x = 12 (Divide both sides by 6)
x = 2
Check:
8(2) - 11 = 2(2) + 1
16 - 11 = 4 + 1
5 = 5

8x – 11 = 2x + 1
8x –2x =11 + 1
6x=12
x=12/6
x=2.

We start with
8x - 11 = 2x + 1
First we want to get x all on the same side of the equal sign so we subtract 2x from both sides:
-2x + 8x - 11 = 2x + 1 - 2x
which is the same as
6x - 11 = 1
Now we want to get x all by itself so we add 11 to both sides
11 + 6x - 11 = 1 + 11
which is the same as
6x = 12
then all we need to do is do is divide both sides by 6
6x / 6 = 12 / 6
which is the same as
x=2
Ta Da!

unknown ( with the x ) goes to the left of = sign
knowns ( withiout the x ) goes to the right of the = sign
when they go to the other side they change sign :
8x – 11 = 2x + 1
8x - 2x = 1 + 11
6x=12
x=2
Now give me 10 points because I explained this so well
