So we shall do this like 

 

9k - 4 =6 x 9 + k

 

now we will first multiplt 6 and 9

 

9k - 4 = 54 + k

 

now we shall move them with their likes!

 

9k - k = 54 + 4

 

we have changed signs as we change places!now simply add and subtract!

 

8k = 60

 

k = 60/8 

 

now i hope you can divide yourself!

 

i posted this answer becoz happy , we just dont have to answer, we gotta tell them how we got the answer.....not just doin our duty.....if anon doesnt get it......wheres our pay?

$${\mathtt{9}}{\mathtt{\,\times\,}}{\mathtt{k}}{\mathtt{\,-\,}}{\mathtt{4}} = {\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{k}} \Rightarrow {\mathtt{k}} = {\frac{{\mathtt{29}}}{{\mathtt{4}}}} \Rightarrow {\mathtt{k}} = {\mathtt{7.25}}$$

Yes where is our pay.

I even looked under the bed but I didn't find it !!

 

 

Yes happy I like that you can use the calc so well but you need to learn how to do thes so that you can show the working  and do it for yourself when you need to.  :)

 

Rosala, what is 54+4    ??    LOL
