Given equation: We are given the equation p+12=30. To find the value of p, we need to isolate p on one side of the equation. We can do this by subtracting 12 from both sides of the equation.Calculation: p+12−12=30−12
Isolating p: After performing the subtraction, we get p=18.Calculation: p=30−12=18
Solution verification: We check our solution by substituting p back into the original equation to ensure that the left side equals the right side.Calculation: 18+12=30
