1. The problem asks if the number 2 is a solution to the equation $3 - p = 1$. 2. Substitute $p = 2$ into the equation to check. 3. Calculate the left side: $3 - 2 = 1$. 4. Since the left side equals the right side ($1 = 1$), the equation is true for $p = 2$. 5. Therefore, the answer is **yes**, 2 is a solution to the equation.
