Answer 2

To solve the inequality 3x + 7 > 5(x + 2) - (2x + 1), we can start by simplifying both sides of the inequality and then solving for x.

Let's simplify the expression step by step:

3x + 7 > 5(x + 2) - (2x + 1)

First, distribute 5 to (x + 2) and distribute -1 to (2x + 1):

3x + 7 > 5x + 10 - 2x - 1

Combine like terms:

3x + 7 > 3x + 9

Now, let's isolate the variable x. Subtract 3x from both sides of the inequality:

3x - 3x + 7 > 3x - 3x + 9

7 > 9

Since 7 is not greater than 9, the inequality is false.

Therefore, there is no solution to the inequality 3x + 7 > 5(x + 2) - (2x + 1).
