Solve the equation below. Please show all of your work

Damon,
7^ [log_7(x + 3/7)]
= x + 3/7 = 7^2 = 1/49
x + 3/7 = 1/49
x = 21/49  1/49 = 22/49

anon,
You make it look so easy and I have been pounding my head on the wall. Thank you!

algebra 
Damon,
except for the sign error
7^ [log_7(x + 3/7)]
= x + 3/7 = 7^2 = 1/49
x + 3/7 = 1/49
x = 21/49 + 1/49 = 20/49
