Part 1
Solve the equation and check the solution.
pminus31equalsminus20

Answer 1

To solve the equation \( p - 31 = -20 \), follow these steps:

1. **Add 31 to both sides** of the equation to isolate \( p \):
\[
p - 31 + 31 = -20 + 31
\]
This simplifies to:
\[
p = 11
\]

2. **Check the solution** by substituting \( p = 11 \) back into the original equation:
\[
11 - 31 = -20
\]
Simplifying the left side gives:
\[
-20 = -20
\]
Since both sides are equal, the solution \( p = 11 \) is correct.

**Final Solution:**
\[
p = 11
\]
