To solve the equation \( x + 12 = 20 \), we need to isolate \( x \). Here’s how you can do it:

1. Subtract 12 from both sides of the equation to eliminate the 12 on the left side:
   \[
   x + 12 - 12 = 20 - 12
   \]
   
2. Simplifying both sides gives:
   \[
   x = 8
   \]

So, the solution is \( x = 8 \).

2. What happens if you subtract instead of add on both sides of an equation?
3. How do you solve an equation with negative numbers, like \( x - 7 = 10 \)?
4. How would you solve the equation if it were \( 2x + 12 = 20 \) instead?
5. What is the next step after isolating \( x \) in a more complex equation?

**Tip:** Always perform the same operation on both sides of an equation to maintain equality.
