Q. Solve for the exact value of x.6ln(7x+1)+8=−10Answer:
Isolate natural logarithm term: Isolate the natural logarithm term.We start by subtracting 8 from both sides of the equation to isolate the term with the natural logarithm.6ln(7x+1)+8−8=−10−86ln(7x+1)=−18
Divide to solve natural logarithm: Divide both sides by 6 to solve for the natural logarithm of the expression.66ln(7x+1)=6−18ln(7x+1)=−3
Exponentiate to remove logarithm: Exponentiate both sides to remove the natural logarithm.eln(7x+1)=e−37x+1=e−3
Subtract to solve for 7x: Subtract 1 from both sides to solve for 7x.7x+1−1=e−3−17x=e−3−1
Divide to solve for x: Divide both sides by 7 to solve for x.77x=7e(−3)−1x=7e(−3)−1
