To solve the inequality \( x + 10.5 < 20.2 \), we first need to isolate \( x \).
-
Subtract 10.5 from both sides:
\[ x < 20.2 - 10.5 \]
-
Perform the subtraction:
\[ x < 9.7 \]
Now, to express this inequality with \( x \) first, we can rewrite it as:
\[ x < 9.7 \]
So, the final answer is:
\[ x < 9.7 \]
