Q. If 18+k=30 18+k=30 , what is the value of k k ?
  1. Identify the equation: Identify the equation to solve for kk.\newlineWe have the equation 18+k=3018 + k = 30, and we need to find the value of kk.
  2. Isolate the variable: Isolate the variable kk on one side of the equation.\newlineTo do this, we subtract 1818 from both sides of the equation to get kk on its own.\newlinek=30−18k = 30 - 18
  3. Perform the subtraction: Perform the subtraction to find the value of kk.k=12k = 12
