Question 1150939: 1)how do i graph this linear equation
x>2
2)what is the solution of the equation
4x + 9 = 24
my solution pls confirm if correct
x=18
3)which step should i take to solve the equation x-11=45 should i add 45 friom both sides
4) what is the value of x in x-9 inequality of 10 my ans x is inequality of -1 pls confirm if correct
5)what is solution for the inequality x + 1 < 3 using properties of equality? my ans x inequality 2 pls confirm

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%2F4.      ANSWER


         CHECK.  Substitute the found value x= 15%2F4 into the left side of the given equation and make calculations

                        4x + 9 = 4%2A%2815%2F4%29 + 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  (!)
