quick math question

2(Absolute value mark)x+6(Absolute value mark)=10

work please! thanks for help if you can X_X

[Maguspk]

|x+6|=5 ?

Then maybe

x = (5-6)

I don't fucking know how absolute values work anymore... but I don't see it's purpose here besides being gay and useless.

It might also mean:

x = 5-6 and x = -5-6 but I don't fucking know, I think I'm right up above.

uh
u mean this?
2|x|+|6|=10?

It's |x| = 2 >_>.

Or I could be totally off, lol.
Haven't done Algebra in like 2 years, kinda slipped my mind.
Calculus and Differential Equations is where it's at.

Actually I'm probably totally wrong, because I don't understand the way you wrote out the problem..

2|x+6| = 10

Absolute value act like parenthesis, except that the result inside can be either positive or negative

2|x+6| = 10
|x+6| = 5
x+6 = -5 AND x+6=5
x=-11 x=-1

[edit]
did a stupid typo (swaped 6 and 5)

OP did you mean:

2|x+6| = 10

?

2[x + 6] = 10

First you have to isolate the numbers inside the abs. value brackets. So you divide 2 out of there. Divide 2 from 10 as well.

[x + 6] = 10

You're left with the absolute value of x + 6 = 10, but since absolute value can be negative inside the brackets but turn out to be positive outside, you create two new problems to solve.

x + 6 = 5
x + 6 = -5

At this point you simply find out what x is in both problems, then you list it as a set.

x = { -1, -11}

If 2|x+6|=10 then |x+6|=5

This means that x+6 = 5 or x+6 = -5. Those two equations have solutions -1 and -11 respectively. You can check the answer by substituting these values back into the original equation.

This is correct.

Yeah, that last post is correct, I just didn't understand his way of writing it.
When you take the opposite value of one side of the equation you have to take the opposite of the other side of the equation as well, so it becomes 2 equations then you solve for X and will get 2 values for it.
