Question

Help Please!


Solve for x
-ax +4b>9

Answer 1

\[ x <\frac{ 9-4b }{a }\]

Answer 2

take 4b on otherside

Answer 3

\[x <\frac{ -4b+9 }{ a }\]

Answer 4

\[x > \frac{ 4b+9 }{ -a }\]

Answer 5

these are the choices. So how do I solve for x here?

Answer 6

can you show me the steps?

Answer 7

like this @gorv ?

Answer 8

so what would be the next step?

Answer 9

-ax +4b-4b> 9 - 4b

Answer 10

@lalaly can you help me to understand the process

Answer 11

-ax<9-4b

Answer 12

now ax ix negative ........so make it positive...by multiplying wiith -
and due to this inequality also changes

Answer 13

ax>-(9-4b)
now move a on other side that"s it

Answer 14

I am still bit confuse here. Do we need to divide both side or multiplying ? I thought divide to make x alone

Answer 15

did you mean like this ? -ax*ax >- (9-4b)

Answer 16

@wolfe8

Answer 17

can you help me bit with this ?

Answer 18

@terenzreignz

Answer 19

Remember that you are dividing by -a

Answer 20

-ax/-a > 9-4b/-a

x > 9-4b/a

like this?

@ajprincess can you help me with this?

Answer 23

Solve for x
-ax +4b>9

We want to isolate x. One of the easier ways of doing this is to make the ax term positive. We can do that by adding ax to both sides, as follows:

-ax + 4b > 9
+ax +ax
-----------------
4b > 9 + ax

To isolate the ax term, subtract 9 from both sides of this inequality:

4b > 9 + ax
-9 -9
------- ------
4b-9 > ax

Finally, isolate x by dividing both sides of the inequality by a:

4b-9 > ax
------ ---
a a

Thus, \[\frac{ 4b-9 }{ a }>x\],

Answer 24

or\[x<\frac{ 4b-9 }{ a }\]

Answer 25

thanks so much @mathmale helping me to understand this!!!!

Answer 26

Very happy to do it! See you again.

Answer 27

:) thanks alot again!!!

Answer 28

Thanks so much all of you for coming here and trying hard to help me @wolfe8 @gorv!!!!! And I am really sorry for troubling all of you

Thank you @ajprincess coming here for help :)

Answer 30

There is problem it is not truly correct I got this answer earlier and it was wrong @mathmale :(

Answer 31

I did not noticed when you're showing step

Answer 32

would you please go back to the very beginning and make sure, absolutely sure, that you've copied the homework problem correctly?

Answer 33

yep i did correctly

Answer 34

@satellite73

Answer 35

Let's try a different method and see whether that produces a different result or not. There can be only one correct result, and that result should be independent of the method used to obtain it.

Answer 36

Solve for x: -ax + 4b > 9

Isolate -ax by subtracting 4b from both sides: (you do it, please)

Answer 37

-ax +4b-4b > 9 - 4b like this?

Answer 38

Yes. that reduces to -ax > 9-4b.

Our next task is to isolate x.

To do this, we must divide both sides of the inequality above by -a AND we must reverse the direction of the inequality sign (because of dividing by a (-) number).

-ax > 9-4b
--- -----
-a -a
9-4b
results in x < ----------
-a

and this is equivalent to
4b-9
x<-------
a

Answer 39

thanks so much for help and I am really for bother you again and again. Please forgive me
