Identify Goal: Identify the goal of the problem.We need to find the value of k in the equation −30+k=22. To do this, we will isolate k on one side of the equation.
Add 30: Add 30 to both sides of the equation to isolate k.−30+k+30=22+30This simplifies to:k=52
Check Solution: Check the solution by substituting the value of k back into the original equation.−30+52 should equal 22.22=22This is true, so our solution for k is correct.
