Question

реши уравнения x+75=125•3 x-75=125•3 x•10=250 x:10=250 х:7=140 140:х=7 32:х=32 32•х=32

Answer 1

x + 75 = 125 * 3

х + 75 = 375

х = 375 - 75

х = 300

300 + 75 = 125 * 3

       375 = 375

х - 75 = 125 * 3

х - 75 = 375

х = 375 + 75

х = 450

450 - 75 = 125 * 3

      375 = 375

х * 10 = 250

х = 250 : 10

х = 25

25 * 10 = 250

   250 = 250

х : 10 = 250

х = 250 * 10

х = 2 500

2 500 : 10 = 250

        250 = 250

х : 7 = 140

х = 140 * 7

х = 980

980 : 7 = 140

     140 = 140

140 : х = 7

х = 140 : 7

х = 20

140 : 20 = 7

          7 = 7

32 : х = 32

х = 32 : 32

х = 1

32 : 1 = 32

   32 = 32

32 * х = 32

х = 32 : 32

х = 1

32 * 1 = 32
