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 = . ANSWER
CHECK. Substitute the found value x= into the left side of the given equation and make calculations
4x + 9 = + 9 = 15 + 9 = 24. ! Correct !

In order to learn other subjects mentioned in your post,
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, it will be much easier to tutors communicate with you.
Also, it will be much easier to YOU communicate with the tutors and understand their instructions.
Happy learning (!)
Come again to this forum soon to learn other subjects (!)
===============
It is the IRON rule of this forum
One and only one problem/question per post !
It is not because we want to increase the number of posts . . .
It is because we want to better serve your requests (!)
