Question

номер 458 решить уравнение

Answer 1

1) 19х = 95

   х = 95 : 19

   х = 5

---------------------

19 * 5 = 95

    95 = 95

2) х * 22 = 132

    х = 132 : 22

    х = 6

-------------------------

6 * 22 = 132

   132 = 132

3) 38х - 16х = 1 474

   22х = 1 474

   х = 1 474 : 22

  х = 67

---------------------------------

38 * 67 - 16 * 67 = 1 474

   2 546 - 1 072 = 1 474

                1 474 = 1 474

4) у + 27у = 952

   28у = 952

   у = 952 : 28

   у = 34

--------------------------------

34 + 27 * 34 = 952

     34 + 918 = 952

            952 = 952

5) х : 25 = 16

   х = 16 * 25

   х = 400

--------------------------

400 : 25 = 16

          16 = 16

6) 324 : х = 27

   х = 324 : 27

   х = 12

-------------------------

324 : 12 = 27

       27 = 27
