Q. How many solutions does this equation have?\newline8n−9=9n8n - 9 = 9n\newlineChoices:\newline(A)no solution\newline(B)one solution\newline(C)infinitely many solutions
  1. Move terms to one side: Simplify the equation by moving all nn terms to one side.8n−9n=98n - 9n = 9−1n=9-1n = 9
  2. Simplify and isolate nn: Divide both sides by −1-1 to solve for nn.n=9−1n = \frac{9}{-1}n=−9n = -9
