Question

a ) \(\left|x-5\right|=0\)

b ) \(\left|x-4\right|=0\)

Answer 1

a)|x-5|=0

      Suy ra:x-5=0

                  x=5

Vậy x=5

b)|x-4|=0

      Suy ra:x-4=0

                  x=4

Vậy x=4

Answer 2

a ) \(\left|x-5\right|=0\)

\(\Rightarrow x=0+5\)

\(\Rightarrow x=5\)

b ) \(\left|x-4\right|=0\)

     \(\Rightarrow x=0+4\)

\(\Rightarrow x=4\)

Answer 3

Ix - 5I = 0

=> x - 5 = 0

=> x = 5

Ix - 4I = 0

=> x - 4 = 0

=> x = 4

Answer 4

a) | x-5 | = 0 

=> x-5    = 0

=>        x= 0+5

=>        x= 5

Vậy x = 5

b) | x-4 | = 0

=> x-4    = 0

=>       x = 0+4

=>       x= 4

Vậy x = 4

Answer 5

a) \(\left|x-5\right|=0\)

\(\Rightarrow x-5=0\)

\(x=0+5\)

\(x=5\)

Vậy \(x=5\)

b) \(\left|x-4\right|=0\)

\(\Rightarrow x-4=0\)

\(x=0+4\)

\(x=4\)

Vậy \(x=4\)
