|
|
I'm failing math right now so I need help on these questions.
| Code: |
1. -6+|x-4|=-6
2. |x-42.04|=23.24
3. 8=7-|x|
4. 9=7-|x+2|
5. 2|2x+8|+(2 x 3x) = 180
6. 8-2(x-5)=x+3
7. -2x-5.75=13.25
|
Show how to solve with the solution! Thanks

No offense, but how can you be failing math with those questions?
I suggest you try to the questions yourself because you're not going to learn from people giving you the solutions on a plate.

just put all the like terms on one side, and by like terms, I mean:
(numbers) = (variable)
Just remember if you move a number or a variable to the other side, you must invert the operation sign attached.
eg,
2x = 3x + 5
-5 = 3x - 2x
etc.
Also, if its in brackets, don't change the operation sign inside it, only outside.

1. -6+|x-4|=-6
First, add 6 to both sides:
|x-4|=0
Second, add 4 to both sides:
|x|=4
Since absolute value=positive only:
x=4,-4
2. |x-42.04|=23.24
First, this is an easy one, add 42.04 to both sides:
|x|=65.28
Second, absolute value=positive only:
x=65.28, -65.28
Get the pattern and do the rest yourself.
If I'm an 8th grader and i did all this stuff last year, you can do it too.
It is your homework, and if you are just trying to cheat, you're cheating yourself, so choose wisely.

If you actually read through it, he only showed how to do it using problem 1 as an example.
