Q. How many solutions does this equation have?\newline5y=5y85y = 5y - 8\newlineChoices:\newline(A)no solution\newline(B)one solution\newline(C)infinitely many solutions
  1. Analyze Equation: Analyze the equation 5y=5y85y = 5y - 8. We start by looking at the equation and seeing if we can simplify or rearrange any terms.
  2. Subtract to Isolate yy: Subtract 5y5y from both sides of the equation to try to isolate yy.5y5y=5y85y5y - 5y = 5y - 8 - 5yThis simplifies to:0=80 = -8
  3. Evaluate Result: Evaluate the result of the simplification.\newlineThe equation 0=80 = -8 is a contradiction because 00 can never equal 8-8. This means that there is no value of yy that can satisfy the equation.
  4. Conclude Number of Solutions: Conclude the number of solutions based on the contradiction. Since we have a contradiction, the equation has no solution.
