log_7(x + 3/7) = -2

• algebra -

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

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

• algebra -

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
