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
