Final answer:

To solve the inequality, distribute and combine like terms. Divide by -3.5 to isolate x. The solution is x < -6.71.

Step-by-step explanation:

To solve the inequality, we need to simplify the expression first. Distribute the -1.5 and -2.5 to the terms inside the parentheses:

-1.5(4x + 1) > 24.5 - 2.5(x + 1)

-6x - 1.5 > 24.5 - 2.5x - 2.5

Combine like terms:

-6x - 1.5 > 22 - 2.5x

Add 2.5x to both sides:

-6x + 2.5x - 1.5 > 22

-3.5x - 1.5 > 22

Add 1.5 to both sides:

-3.5x > 23.5

Divide by -3.5 (remember to switch the inequality sign when dividing by a negative number):

x < -23.5/3.5

Simplify the fraction:

x < -6.71

The solution set to the inequality is (-infinity, -6.71).
