Answer
\( x = 8.3 \)
Solution
To find the value of \( x \) in the equation:
\[
8.5 + x = 16.8
\]
**Step 1:** Subtract 8.5 from both sides of the equation to isolate \( x \).
\[
x = 16.8 - 8.5
\]
**Step 2:** Perform the subtraction.
\[
x = 8.3
\]
**Answer:**
\[
x = 8.3
\]

Explain 
Simplify this solution Bonus Knowledge
To solve for \( x \), you need to isolate the variable. Start by subtracting \( 8.5 \) from both sides of the equation. This gives you \( x = 16.8 - 8.5 \). When you perform the subtraction, you find that \( 16.8 - 8.5 = 8.3 \). So the value of \( x \) is \( 8.3 \)! One handy tip when working with decimals is to line up the numbers vertically by the decimal point to avoid mistakes in addition or subtraction. If you’re subtracting \( 8.5 \) from \( 16.8 \), write it as: ``` 16.8 - 8.5 ______ ``` This makes it easier to see what you’re doing and helps prevent errors!
