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

2 + 7^6x = 5

7^6x = 5-2 = 3

take natural log both sides

ln (7^6x) = ln 3

6x . ln 7 = ln 3

6x = ln 3 / ln 7

6x = 1.098 / 1.946   ..............use log tables or calculator to find values of ln 3 and ln 7

6x = 0.5645

x = 0.5645/6

x = 0.094   ...................Answer
