Q. Solve for the exact value of x x .\newline6ln(7x+1)+8=10 6 \ln (7 x+1)+8=-10 \newlineAnswer:
  1. Isolate natural logarithm term: Isolate the natural logarithm term.\newlineWe start by subtracting 88 from both sides of the equation to isolate the term with the natural logarithm.\newline6ln(7x+1)+88=1086\ln(7x+1) + 8 - 8 = -10 - 8\newline6ln(7x+1)=186\ln(7x+1) = -18
  2. Divide to solve natural logarithm: Divide both sides by 66 to solve for the natural logarithm of the expression.\newline6ln(7x+1)6=186\frac{6\ln(7x+1)}{6} = \frac{-18}{6}\newlineln(7x+1)=3\ln(7x+1) = -3
  3. Exponentiate to remove logarithm: Exponentiate both sides to remove the natural logarithm.\newlineeln(7x+1)=e3e^{\ln(7x+1)} = e^{-3}\newline7x+1=e37x + 1 = e^{-3}
  4. Subtract to solve for 7x7x: Subtract 11 from both sides to solve for 7x7x.\newline7x+11=e317x + 1 - 1 = e^{-3} - 1\newline7x=e317x = e^{-3} - 1
  5. Divide to solve for x: Divide both sides by 77 to solve for xx.7x7=e(3)17\frac{7x}{7} = \frac{e^{(-3)} - 1}{7}x=e(3)17x = \frac{e^{(-3)} - 1}{7}
