Identify Goal: Identify the goal of the problem.We need to find the value of n that satisfies the equation 27=15+n.
Isolate Variable: Isolate the variable n on one side of the equation.To do this, we subtract 15 from both sides of the equation to get n by itself.27−15=15+n−15
Perform Subtraction: Perform the subtraction on both sides.27−15=1215−15=0So, the equation simplifies to:12=n
Check Solution: Check the solution.Substitute n=12 back into the original equation to verify if it is correct.27=15+1227=27Since both sides of the equation are equal, the solution n=12 is correct.
