Question

Help me

4x :17 = 0

7x - 8 = 713

8(x - 3) = 0

Answer 1

* 4x : 17 = 0 

4x = 0

x = 0 : 4 = 0

* 7x - 8 = 713

7x = 713 + 8

7x = 721

x = 721 : 7 = 103

* 8(x - 3) = 0

8x - 24 = 0

8x = 24

x = 24 : 8

x = 3

Nhớ k cho mình với nhá!

Answer 2

4x : 17 = 0

=> 4x = 0 x17 = 0

=> x = 0 : 4 = 0

7x - 8 = 713

=> 7x = 713 + 8 = 721 

=> x = 103

8( x- 3 ) = 0 

=> x-3 = 0 : 8 = 0

=> x = 0 + 3 = 3

Answer 3

\(4x:17=0\)

\(=>4x=0\)

\(=>x=0\)

\(7x-8=713\)

\(=>7x=721\)

\(=>x=103\)

\(8\left(x-3\right)=0\)

\(=>x-3=0\)

\(=>x=3\)

Answer 4

a, 

4x : 17 = 0

4x        = 0 x 17

4x        = 0

=> x = 0

b, 

7x - 8 = 713

7x      = 713 + 8

7x      = 721

  x      = 721 : 7

  x      = 103

c, 

8(x - 3) = 0

   x - 3  = 0 : 8 

   x - 3  = 0 

   x       = 0 + 3

   x       = 3

Answer 5

4x : 17 =0

4x        = 0 x 17 = 0

   x         =  0 : 4

   x            = 0

7x - 8 = 713

7x     =  713 + 8 = 721

  x     =  721 : 7

  x     = 103

8.(x-3) = 0

   x - 3  = 0 : 8 = 0

   x       =  0 + 3

  x       =  3

Answer 6

4x:17=0

     4x=0.17

     4x=0

       x=0:4

       x=0

7x-8 =713

    7x=713+8

    7x=721

      x=721:7

      x=103

8(x-3)=0

  (x-3)=0:8

  (x-3)=0

    x-3=0

       x=0+3

       x=3
