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

2 + 7^6x = 5  

 7^6x = 3 

e^(6xln(7)) = e^(ln(3)) 

 6xln(7) = ln(3)

x = ln(3) / 6ln(7) 

x = 0.0940

test it 

pleas ask if you don't undestand something 

Good Luck 

Please let me know if you need any clarification. I'm always happy to answer your questions.
