Step-by-step explanation:

1. x-5=18

For this one, we add 5 to both sides, therefore canceling it out.

x-5=18

+5  +5

x=23

2. x+2=-1.4

Now for number 2, we subtract 2 from both sides.

x+2=-1.4

 -2   -2

x=-3.4

3. x-5.5=-8.2

     +5.5 +5.5

x=-2.7

4. 3.4-x=1.88

   -3.4    -3.4

-x=-1.52

Now this gets a bit weird. The x is negative, but we can fix that. There was a secret 1 there all along.

-1x=-1.52

Just divide -1.

-1x=-1.52

/-1    /-1

x=1.52
