En una granja, por cada 7 pollos hay 6 corderos, y por cada 2 corderos hay 3 vacas. Si se cuentan 1210 cabezas. El total de vacas que hay en la granja es​

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:

yes they are the same

then

-11/5> -11/3
