Question

15-(x-5)=-1

Answer 1

15-(x-5)=-1

(x-5)=15+1

x-5=16

x=21

Answer 2

(x-5)=15-(-1)

(x-5)=16

x     = 16+5

x     = 21

tích nha

Answer 3

15 - ( x - 5 ) = -1

x - 5 = 15 - ( -1 )

x - 5 = 16

x = 16 + 5

x = 21

Answer 4

=> x-5=15-(-1)

=> x-5=16

=> x=16+5

=> x=21

Answer 5

\(15-\left(x-5\right)=-1\)

                 \(x-5=15-\left(-1\right)\)

                  \(x-5=16\)

                  \(x=16+5\)

                  \(x=21\) 

          

Answer 6

15 - (x - 5 ) =-1

        x - 5 = 15 - (-1)

        x - 5 = 16

        x     = 16 + 5

        x     = 21

      Vậy x = 21
