Q. If 18=n−18 18=n-18 , what is the value of n n ?
  1. Understand the equation: Understand the equation.\newlineThe equation given is 18=n−1818 = n - 18, which means that when 1818 is subtracted from nn, the result is 1818.
  2. Add 1818 to both sides: Add 1818 to both sides of the equation to isolate n.\newline18+18=n−18+1818 + 18 = n - 18 + 18\newlineThis simplifies to:\newline36=n36 = n
  3. Verify the solution: Verify the solution.\newlineSubstitute nn with 3636 in the original equation to check if the equation holds true.\newline18=36−1818 = 36 - 18\newline18=1818 = 18\newlineSince both sides of the equation are equal, the solution is correct.
