Solve the equations by trial-and-error method.
`23=12+p`

Answer

To solve the equation \( 23 = 12 + p \) using the trial-and-error method, we will follow these steps:

### Step 1: Understand the equation
We need to find the value of \( p \) such that when we add it to 12, the result equals 23.

### Step 2: Rearrange the equation
We can rearrange the equation to isolate \( p \):
\[ p = 23 - 12 \]

### Step 3: Calculate the value of \( p \)
Now, we can calculate:
\[ p = 23 - 12 = 11 \]

### Step 4: Verify the solution
To verify, we substitute \( p \) back into the original equation:
\[ 12 + p = 12 + 11 = 23 \]

Since both sides of the equation are equal, our solution is correct.

### Final Answer
The value of \( p \) is \( 11 \).
