To solve the inequality \( x + 10.5 < 20.2 \), we want to isolate \( x \). Here are the steps:
-
Subtract \( 10.5 \) from both sides of the inequality:
\[ x + 10.5 - 10.5 < 20.2 - 10.5 \]
-
This simplifies to:
\[ x < 20.2 - 10.5 \]
-
Now, calculate \( 20.2 - 10.5 \):
\[ 20.2 - 10.5 = 9.7 \]
-
Therefore, the inequality can be rewritten as:
\[ x < 9.7 \]
Now, you want the variable \( x \) to come first. So, we can write this as:
\[ x < 9.7 \]
This means that \( x \) can take any value less than \( 9.7 \).
Explanation:
- We started with the inequality \( x + 10.5 < 20.2 \) and aimed to isolate \( x \).
- By subtracting \( 10.5 \) from both sides, we found the maximum value \( x \) can take, which is \( 9.7 \).
- Finally, we expressed the result in the standard form with \( x \) coming first in the inequality.
