Julia has read her favorite book 6 times,This is 3 times more than her Kami.How many times has Kami read the book?
motikmotik

Answer:    The answer is:  " 2 " .  

_______________________________________________

        → Kami has read the book "<u>  2 (two)  </u>" times.

_______________________________________________

Step-by-step explanation:

_______________________________________________

Let "J" represent the number of times julia has read the book.

Let "K" represent the number of times Kami has read the book.

J = 6 ;  

J = 3K ;  

Solve for "K" ;

J = 6 = 3K ;

→ 6 = 3K ;

 ↔  3K = 6 ;

Divide each side of the equation by "3" ;

to isolate "K"  on one side of the equation; & to solve for "K" :

→  3K / 3  =  6 / 3 ;

to get:

  K = 2 .

_______________________________________________

 The answer is:  " 2 " .

        → Kami has read the book "<u>  2 (two)  </u>" times.
