3. Aşağıda verilen problemleri bir bilinmeyenli denklem kurarak çözünüz a) Farklar 80 olan iki sayıdan büyük sayı-
nin 1/5'i ile küçük sayının 1/2'si arasında-
ki fark 1'dir. Buna göre, büyük sayı kaçtır?
​

i believe it's a.

i'm not sure on this one, most likely correct.

my guess is

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

a reflection across the x axis and a 90 degree rotation left and right.
