Q. Solve for the exact value of x.4ln(7x+3)+19=43Answer:
Isolate logarithmic expression: First, we need to isolate the logarithmic expression by subtracting 19 from both sides of the equation.4ln(7x+3)+19−19=43−194ln(7x+3)=24
Divide by 4: Next, we divide both sides by 4 to solve for the natural logarithm of (7x+3).44ln(7x+3)=424ln(7x+3)=6
Exponentiate both sides: Now, we will exponentiate both sides to remove the natural logarithm, using the property eln(x)=x.eln(7x+3)=e67x+3=e6
Subtract 3: Subtract 3 from both sides to isolate the term with x.7x+3−3=e6−37x=e6−3
Divide by 7: Finally, divide both sides by 7 to solve for x.77x=7e6−3x=7e6−3
