Sagot :
[tex]\\ \rm\longmapsto 4-|x|=1[/tex]
- Take 4 right
[tex]\\ \rm\longmapsto -|x|=1-4[/tex]
[tex]\\ \rm\longmapsto -|x|=-3[/tex]
[tex]\\ \rm\longmapsto |x|=3[/tex]
Step-by-step explanation:
- 4-|x|=1
By subtracting 4 from both sides, we get
- 4-|x|-4=1-4
- -|x|=-3
Here for cancelling minus we can multiply or divide both sides by -1,
- -|x|×-1=-3×-1
- |x|=3
Or,
- -|x|÷-1=-3÷-1
- |x|=3
Hence the value of |x| is 3.
