Re: Where are yall?
Mmmmh Maths
|x+1| + |x| = 3
We must change/transform |x+1| because he is "nasty"
|x+1| = x+1 (x+1) >= 0
|x+1| = -(x+1) (x+1) == 0[/u]
x >= -1
Now we should care of |x| : ( |x| = x if x >= 0 .... |x| = -x if x = -1 == 0
if x >= 0 :
x+1 >= 0
thus : |x+1| + |x| = 3
x+1 + x = 3
2 x = 2
x = 1
CCL : x = 1 "for" x >= 0
if -1 == 0 but x = x+1 -x = 3
1 = 3 (lol)
CCL : No solution for x € [ -1 ; 0 ] (€ o/)
x+1 = x = - (x+1) - x = 3
-x -1 -x = 3
-2x -1 = 3
-2x = 4
x = -2
CCL : x = -2 for x == suck...

Re: Where are yall?
Oh my god... Now I probably understand it :/
Thank you Syl, that you explained everything that cool...
Unfortunately, I gave this "exam" already to the teacher, so I can't change it xD
I just wrote, something like:
X = -2
BECAUSE:
|-2+1|+|-2|=3
xDDDDD

Re: Where are yall?
In the end it's what we said: -2 and +1 . xDDDDDD Obviously he wrote calculates too and it helps.Leader wrote:Oh my god... Now I probably understand it :/

Re: Where are yall?
The only one problem, is that I didn't write all calculations on the test... So it might look little weird, due that I gave correct answer, but without calculation xD
