let x/y+w/z =2,then the value of y/x+z/w is a)1/2 b) 3/4 c)5 d)2 which one is correct answer please help​

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:
