Q. How many solutions does this equation have?\newline63n=3n6 - 3n = -3n\newlineChoices:\newline(A)no solution\newline(B)one solution\newline(C)infinitely many solutions
  1. Analyze Equation: Analyze the equation 63n=3n6 - 3n = -3n. We want to determine if there are any values of nn that make this equation true.
  2. Simplify Equation: Simplify the equation by moving all terms involving nn to one side.\newlineHowever, we notice that both sides of the equation already have the term 3n–3n. We can subtract 3n–3n from both sides to potentially simplify the equation.\newline63n+3n=3n+3n6 − 3n + 3n = –3n + 3n
  3. Calculate Result: Calculate the result after simplifying. \newline6=06 = 0\newlineThis simplification shows that the terms involving nn cancel each other out, leaving us with a statement that does not involve nn.
  4. Determine Truth Value: Determine the truth value of the simplified statement.\newlineThe statement 6=06 = 0 is false, as 66 is not equal to 00. However, this does not affect the number of solutions to the original equation, as the nn terms have canceled out.
  5. Conclude Solutions: Conclude the number of solutions based on the simplified equation.\newlineSince the nn terms canceled out and we are left with a true statement (if we had 6=66 = 6) or a false statement (as in this case, 6=06 = 0), the original equation does not depend on the value of nn. Therefore, the equation 63n=3n6 - 3n = -3n has infinitely many solutions, as any value of nn will satisfy the equation.
