Q. What value of n n makes the equation true?\newline9n=27 9 n=27 \newline33\newline243243\newline3030\newline1818
  1. Divide by 99: Divide both sides of the equation by 99 to isolate nn.n=279n = \frac{27}{9}
  2. Calculate division: Calculate the division. n=3n = 3
  3. Check solution: Check the solution by substituting nn back into the original equation.9×3=279 \times 3 = 27
  4. Verify equality: Verify that the left side equals the right side.\newline27=2727 = 27
