Direction = Right
Unbalanced
2. Net force = 7 N
Direction = Right
Unbalanced
3. Net force = 25 N
Direction = Left
Unbalanced
4. Net force = 60 N
Direction = Left
Unbalanced
5. Net force = 0
Direction = There is no motion, and it is not moving in any direction, it is at rest.
Balanced
6. Net force = 4 N
Direction = Down
Unbalanced

Hope this helps :)
Step-by-step explanation:
To calculate net force, we must look at the direction it's pointing and the number of Newtons (N). If the arrow/arrows are pointing in the same direction, add the numbers, and the direction would be where the arrow is pointing (left,right,up,down). If the arrow/arrows are pointing in different directions, subtract the bigger and little number, and the direction would be where the bigger number is pointing (left,right,up,down).
It is only balanced when the net force is equal to zero. If the net force equals a number that's not zero like 1 and continuing on forever then it would be unbalanced.
