Answer:
n > 4
Step-by-step explanation:
3n - 7 > n + 1
Move variable to the left side and change its sign
3n - n - 7 > 1
...
3n - 7 > n + 1
Move constant to the right side and change its sign
3n - n > 1 + 7
...
3n - n > 1 + 7
Collect the like terms
2n < 1 + 7
...
3n - n > 1 + 7
Add the numbers
2n < 8
Divide both sides of the inequality by 2
Solution:
n > 4 Answer:
n < 2
Step-by-step explanation:
4n - 5 < 3n - 3
Move variable to the left side and change its sign
4n - 3n - 5 < - 3
...
4n - 5 < 3n -3
Move constant to the right side and change its sign
4n - 3n < - 3 + 5
...
4n - 3n < - 3 + 5
Collect the like terms
n < - 3 + 5
...
4n - 3n < - 3 + 5
Calculate the sum
n < 2
...
Solution:
n < 2
