Question 1150939
.
<pre>


2)  Your answer  x= 18 is not correct, and you can easily check it by substituting the value of x= 18 into the given equation.


    The procedure of the solution to the given equation is as follows.


        4x + 9 = 24.

            Subtract 9 from both sides.  You will get

        4x + 9 - 9 = 24 - 9,    or, canceling 9 on the left side

        4x = 15.

            Now divide the last equation by 4 (both sides).  You will get

         x = {{{15/4}}}.      <U>ANSWER</U>


         <U>CHECK</U>.  Substitute the found value x= {{{15/4}}} into the left side of the given equation and make calculations

                        4x + 9 = {{{4*(15/4)}}} + 9 = 15 + 9 = 24.   ! Correct !

In order to learn other subjects mentioned in your post, 


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;P L E A S E


divide/separate your post in parts,


placing one and only one question/problem into each post.



In this way, &nbsp;it will be much easier to tutors communicate with you.


Also, &nbsp;it will be much easier to &nbsp;<U>YOU</U> &nbsp;communicate with the tutors and understand their instructions.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Happy learning &nbsp;(!)

===============


It is the &nbsp;<U>IRON &nbsp;rule</U> &nbsp;of this forum


<H3>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;One and only one problem/question per post !</H3>


It is not because we want to increase the number of posts . . . 


It is because we want to better serve your requests &nbsp;(!)
