Rewrite without absolute value <br><br> y=|x−5|+|x+5|, if x<−5<br><br> thank you

ioda

y = | x -5| + |x+5|

as range of x is

-5 < x < 5

we can see if we put x = 0 we get

y = 10

we put any value of x in given range first term is always negative without absolute. and 2nd term is always positive

y = | x -5| + |x+5|

= -( x-5) + x + 5

= - x + 5 + x + 5

= 10

y = 10 where -5 < x < 5
