Identify Equation: Identify the equation that needs to be solved.The equation given is p+12=30. We need to find the value of p.
Isolate Variable: Isolate the variable p by subtracting 12 from both sides of the equation.p+12−12=30−12This simplifies to p=18.
Check Solution: Check the solution by substituting the value of p back into the original equation.p+12=3018+12=3030=30The left side of the equation equals the right side, so the solution is correct.
