If x =2/3y and y = 18, what is the value of 2x - 3

when x=12.

Step-by-step explanation:

Given : If and

To find : The value of ?

Solution :

The expression given as

Substitute the value of

So, The value of x is 12.

Substitute x in ,

Therefore, when x=12.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
