Answer:
1, 3, 4, 5, 6 are all correct
Step-by-step explanation:
1. x - 2 = 0
+2 +2
solution: x = 2
3. 5 - x = 3
-5 -5
-x = -2 (divide both sides by -1 because x equals 1. A negative divided by a negative equals a positive)
solution: x = 2
4. 10 = 5x (you divide 5 on both sides to get x by itself) 10/5 equals 2 so x=2
5. 1/2x = 1 (you divide both sides so you flip the fraction 2/1 is 2 and 2x1 = 2 so the answer is x=2
6. x^3 = 8 (2x2x2) is equal to 8 so x=2
