2 = 22 + x
2 - 22 = x
x = - 20

You need a line plot thing!
-22 -21 -20 -19 -18 -17 -16 -15 AND SO ON TILL IT GOES TO ONE...
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
I'm not so sure what to do after that!

-x + 2 = 22
-x + 2-2 = 22 -2
-x+ 0 = 20
-x/-1 = 20/-1
x = -20

OK, take a deep breath. Sit down.
The equation is:
-x + 2 = 22.
Take the same amount from each side of the equation:
-x + 2 - 2 = 22 -2 or -x = 20.
Multiply each side by -1:
x = -20.

ok so
subtract the 2 on the right from 22
then you will have -x=20
so then you divide both sides by a -
so you end up with x= -20
-x+2=22
-2 -2
-x=20
-x=20
--- ----
-x -x
x=-20

-x + 2 = 22 ...... subtract 2 from each side
-x + 2 -2 = 22 -2
-x = 20 multiply each side by -1
-x * -1 = 20 * -1
x = -20

-x + 2 = 22
subtract 2 from both sides
-x = 20
divide both sides by negative one
x = -20
