Question

HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEElp

Answer 1

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

Answer 2

Answer:

1, 3, 4, 5, 6

Step-by-step explanation:

2 - 2 = 0

2 + 2 = 4, not 2

5 - 2 = 3

10 = 5(2)

1/2(2) = 1

2^3 = 8
