Answer:

All of the numbers are solutions.

Explanation:

Step 1: Solve for x in the first equation


3x - 1 + 1 > 8 + 1


3x / 3 > 9 / 3


x > 3

Step 2: Solve for x in the second equation


7 - x - 7 > 3 - 7


-x / -1 > -4 / -1

Since you divided by a negative, you must flip the sign.


x < 4

Step 3: Find the number

x > 3 and x < 4

Answer: All of the numbers are solutions.
