Solve ln (5x+1) = 3

OpenStudy (zzr0ck3r):

raise both to be powers of e

Remove the parentheses around the expression 5x+1. 5x+1=3 Since 1 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 1 from both sides. 5x=−1+3

OpenStudy (zzr0ck3r):

\(\ln(5x+1)=3\iff 5x+1=e^3\iff x=\frac{e^3-1}{5}\)

jagr2713 (jagr2713):

5x=−1+3 Add 3 to −1 to get 2. 5x=2 Divide each term in the equation by 5. Divide each term in the equation by 5. Cancel the common factor of 5 in 5x/ Reduce the expression 5x5 by removing a factor of 5 from the numerator and denominator. x=2/5.
