Z - 5 = 5Z - 3
This is what I did:
Z - 5 = 5Z - 3
-5Z -5Z
-6Z - 5 = -3
+5 +5
-6Z=2
Z=-3
What am I doing wrong? Thanks in advance!!

z - 5 = 5z - 3
z = 5z - 3 + 5 (add 5 both the side)
z = 5z + 2
z - 5z = 2 (subtract 5z from both side)
-4z = 2
z = 2/-4 (dvide by -4 )
z = -1/2

Try this:
Z – 5 = 5Z -3
Add 3 to each side: (Z – 5) + 3 = (5Z -3) + 3
Z - 2 = 5Z
Subtract Z from each side: (Z – 2) – Z = 5Z - Z
-2 = 4Z
Divide by 4: -2/4 = 4Z/4
-05 = Z
Z = -0.5

Z - 5 = 5Z - 3
(first bring z to the left, no. to the right. Once you bring over, minus becomes plus and plus becomes minus.
Z - 5Z = -3 + 5
-4Z = 2
so, now you bring -4 over, it will be divide.
Z = -2/4
Z = -1/2

Z - 5 = 5Z - 3
(subtract Z from both sides)
- 5 = 4Z - 3
(Add 3 to both sides)
-2 = 4Z
(Divide both sides by 4)
-2 / 4 = Z
Z = -2/4 = -1/2

u r wrong.
bring the variables to the left side and the numbers to the right
Z - 5Z = -3 + 5
-4Z = 2
Z= 2/-4
Z = -1/2

Z - 5 = 5Z - 3
-5Z -5Z
-6Z - 5 = -3**** Should be -4Z
+5 +5
-6Z=2
Z=-3

z - 5 = 5z - 3
z - 5 - z = 5x - 3 - z
- 5 = 4z - 3
- 5 + 3 = 4z - 3 + 3
-2 = 4z
- 2 / 4 = 4z / 4
- 2 / 4 = z
- 1/ 2 = z
- 0.5 = z
- - - - - - -s-

Take Z from both sides:-
- 5 = 4Z - 3
Add 3 to both sides:-
- 2 = 4z
Divide both sides by 4:-
Z = - (1/2)
