Solve the following inequality.

12x + 40 < 304

To solve the inequality, we can subtract 40 from both sides of the equation:

12x + 40 - 40 < 304 - 40

This simplifies to:

12x < 264

Next, we can divide both sides of the equation by 12 to isolate the variable x:

(12x) / 12 < 264 / 12

This simplifies to:

x < 22

Therefore, the solution to the inequality is x < 22.
