Q. Find the unknown number in each equation:\newline 3+6+m+12+5=303+6+m+12+5=30
  1. Combine Known Numbers: Combine all the known numbers on the left side of the equation.\newlineCalculation: 3+6+12+5=263 + 6 + 12 + 5 = 26
  2. Subtract Sum for mm: Subtract the sum of the known numbers from the total on the right side to solve for mm.\newlineCalculation: 30−26=430 - 26 = 4
