15-0,3<x<15+0,3

The inequality \( 15 - 0.3 < x < 15 + 0.3 \) can be simplified as follows:

1. Calculate the lower bound: \[ 15 - 0.3 = 14.7 \]

2. Calculate the upper bound: \[ 15 + 0.3 = 15.3 \]

Thus, the inequality can be rewritten as: \[ 14.7 < x < 15.3 \]

This means that \( x \) lies between \( 14.7 \) and \( 15.3 \), not inclusive.
