\[2\left| x+2 \right|=5+1=6\] \[\left| x+2 \right|=\frac{ 6 }{ 2 }=3\] \[x+2=\pm3\] find x

yes, remember the abs value can have a + or - value and be true, like the last line above

what about the equation \[2\left| x+2 \right|-1=-5\]
anonymous
  • anonymous
I got zero but i know that's not the answer

--solve for the absolute value quantity.\[\left| something \right| = c\] --set that 'something' equal to + or - c \[something = +c~~~~or~~~~something=-c\]

My first answer was x=1, I'm trying to solve the second equation now. I'm unsure of the answer because I know I'm taking the wrong steps
DanJS
  • DanJS
that one is a bit different, just looked at it
anonymous
  • anonymous
Yes, the second equation is negative
DanJS
  • DanJS
The absolute value is greater than or equal to zero, so that one will not have any answers
anonymous
  • anonymous
my options for that equation is -1 or -5

\[2*\left| x+2 \right|-1=-5\] \[\left| x+2 \right|=-2\] false, no solution
