Answer 1

(3x-10):10=50

3x-10=500

3x=510

x=170

Answer 2

3x-10=500

     3x=510

       x=170

Answer 3

(3x - 10) : 10 = 50

3x - 10 = 500

3x = 510

x = 170

Answer 4

3x - 10 = 500

3x = 510

x = 510 : 3 = 170

Answer 5

\(\left(3x-10\right):10=50\)

\(3x-10=50.10\)

\(3x-10=500\)

\(3x=500+10\)

\(3x=510\)

\(x=510:3\)

\(x=170\)

Vậy x=170.

Chúc em học tốt^^

Answer 6

(3x - 10) : 10 = 50

 3x - 10         = 50 x 10

 3x - 10         = 500

 3x                = 500 + 10

 3x                = 510

   x                = 510 : 3

   x                = 170

Vậy x = 170

Answer 10

(3x - 10) : 10 = 50

         3x - 10 = 50 x 10

         3x - 10 = 500

               3.x = 500 + 10

               3.x = 510

                  x = 510 : 3

                  x = 170

Answer 11

(3x - 10) : 10 = 50

         3x - 10 = 50 x 10

               3.x = 500 + 10

               3.x = 510

                  x = 510 : 3

                  x = 170

Answer 12

(3x - 10) : 10 = 50

         3x - 10 = 50 x 10

               3.x = 500 + 10

               3.x = 510

                  x = 510 : 3

                  x = 170

Answer 13

(3x - 10) : 10 = 50

         3x - 10 = 50 x 10

         3x - 10 = 500

               3.x = 500 + 10

               3.x = 510

                  x = 510 : 3

                  x = 170

Answer 14

(3x - 10) : 10 = 50

         3x - 10 = 50 x 10
