Identify equation and 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 will add 1 to both sides of the equation to get p by itself on one side. This gives us 2+1=−1+1+p.
Perform addition on both sides: Perform the addition on both sides of the equation.On the left side, 2+1 equals 3. On the right side, −1+1 equals 0, so we are left with 3=0+p, which simplifies to 3=p.
Write final value of p: Write down the final value of p.Since 3=p, the value of p is 3.
