Identify Equation & Goal: Identify the equation and the goal.We are given the equation 2=−1+p, and we need to find the value of p.
Isolate Variable p: Isolate the variable p on one side of the equation.To do this, we can add 1 to both sides of the equation to get p by itself on the right side.2+1=−1+p+1
Perform Addition: Perform the addition on both sides of the equation.2+1=3−1+1=0So, the equation now is 3=p.
Write Final Value: Write down the final value of p.Since 3=p, the value of p is 3.
