Solve the logarithmic equation for x.

Thank you for the opportunity to help you with your question!

log(7x + 1) = 2

log(7x + 1) = log(e^2)

7x + 1 = e^2

x = (e^(2) - 1)/7

x = 0.9127

answer incorrect

ln(7x + 1) / ln(10) = 2

ln(7x + 1) = 2ln(10)

ln(7x + 1) = ln(100)

7x + 1 = 100

7x = 99

x = 14.1428

test it

incorrect also

99/7

test :

x = 99/7 =14.1428574
