Full solution

Q. Is (67)(\frac{6}{7}) a solution to the equation 7x8=57x-8=-5 ? Why or why not?
  1. Substitute Value into Equation: Substitute the value (6)/(7)(6)/(7) into the equation 7x8=57x - 8 = -5.\newlineCalculation: 7×(6)/(7)87 \times (6)/(7) - 8.\newlineMath error check:
  2. Simplify Multiplication: Simplify the multiplication 7×677 \times \frac{6}{7}.\newlineCalculation: (7×6)/7=6\left(7 \times 6\right)/7 = 6, because the 77 in the numerator and denominator cancel each other out.\newlineMath error check:
  3. Continue Simplification: Continue the simplification by subtracting 88 from 66.\newlineCalculation: 68=26 - 8 = -2.\newlineMath error check:
  4. Compare Results: Compare the result from Step 33 with the right side of the original equation.\newlineCalculation: 2-2 is not equal to 5-5.\newlineMath error check:
  5. Check Solution: Determine if (6)/(7)(6)/(7) is a solution to the equation by checking if the left side equals the right side after the substitution.\newlineCalculation: Since 25-2 \neq -5, (6)/(7)(6)/(7) is not a solution to the equation 7x8=57x - 8 = -5.\newlineMath error check:
