solve 5x + 12.5 < 23.1

To solve the inequality 5x + 12.5 < 23.1, we need to isolate the variable x on one side of the inequality sign.

Subtract 12.5 from both sides of the inequality:
5x + 12.5 - 12.5 < 23.1 - 12.5
5x < 10.6

Divide both sides of the inequality by 5 to solve for x:
x < 10.6 / 5
x < 2.12

Therefore, the solution to the inequality 5x + 12.5 < 23.1 is x < 2.12.
