Step one, divide both sides by -2
log8(x+1)=4
if the base is 10, and the 8 is together with (x+1): (cannot tell from the way it is written)
8(x+1)=10^4=10000
x+1=1250
x=1249
if the 8 is a base,
8^4=(x+1)
x+1=4096
x=4095
The answer is 4n-25
4 times n is 4 n
and 25 decreased or subtracted from the 4n
thus the answer is 4n-25
