Distribute and Simplify: Step 1: Simplify the equation by distributing the multiplication across the parentheses.Calculation: 18=3(p+1) becomes 18=3p+3.
Isolate Variable: Step 2: Isolate the variable p by subtracting 3 from both sides of the equation.Calculation: 18−3=3p, which simplifies to 15=3p.
Solve for p: Step 3: Solve for p by dividing both sides of the equation by 3.Calculation: 315=p, so p=5.
