Q. If −30+k=22 -30+k=22 , what is the value of k k ?
  1. Identify Goal: Identify the goal of the problem.\newlineWe need to find the value of kk in the equation −30+k=22-30 + k = 22. To do this, we will isolate kk on one side of the equation.
  2. Add 3030: Add 3030 to both sides of the equation to isolate kk.\newline−30+k+30=22+30-30 + k + 30 = 22 + 30\newlineThis simplifies to:\newlinek=52k = 52
  3. Check Solution: Check the solution by substituting the value of kk back into the original equation.−30+52-30 + 52 should equal 2222.22=2222 = 22This is true, so our solution for kk is correct.
