Question

Find a number that is not a solution to 3x-1>8 or 7-x>3

Answer 1

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.
