Answer:

All of the numbers are solutions.

Step-by-step 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.

Answer:

Step-by-step explanation:

The problem is clearly addition, so we can rule out B and C. Associative property is the movement of the parentheses, whereas commutative property is the movement or reorganization of the numbers. The parentheses moved in this problem, so it is associative. I suggest reviewing these properites, they come in handy later and are good to know :)
