To solve the equation P - 12 = -27, we can isolate the variable P by performing inverse operations.
First, we want to get rid of the -12 on the left side of the equation. Since -12 is being subtracted, we can perform the opposite operation, which is addition. Adding 12 to both sides of the equation, we have:
P - 12 + 12 = -27 + 12
This simplifies to:
P = -15
Therefore, the value of P that satisfies the equation is -15.
