Question

 504 : [ 16 - 3 . x ] = 72

272- [4 . x + 15 ] =45

425 - x :8  = 91

293 - 8.27 + x . 25 = 80

dấu chấm là nhân nha !!!

Các bạn làm nhanh nhất mình tick cho !!!!

Answer 1

a,504:[16-3.x]=72

          16-3.x=504:72

          16-3.x=7

          3.x     =16-7

          3.x     =9

            \(\Rightarrow x=3\)

          b,272-[4.x+15] = 45

                   4.x+15  = 272-45

                   4.x+15  = 227

                   4.x        = 227-15

                   4.x        = 212

                      x        = 212:4

                      \(\Rightarrow x=53\)

                     c,425-x:8 =91

                              x:8 =425-91

                              x:8 =334

                              x    =334x8

                              \(\Rightarrow x=2672\)

                     d,  293-8.27+x.25=80

                         293-216 +x.25=80

                         77+x.25         =80

                               x.25         =3

                               \(\Rightarrow x=\frac{3}{25}\)

                         

Answer 2

x = 3

x = 53

x = 2672

x = 3 / 25

ai thấy đúng thì ủng hộ mk nha

Answer 3

504:[16-3x]=72

16-3x=504:72

16-3x=7

3x=16-7

3x=9

x=9:3

x=3

Vậy x=3

272-(4x+15)=45

4x+15=272-45

4x+15=227

4x=227-15

4x=212

x=212:4

x=53

Vậy x=53

425-x:8=91

x:8=425-91

x:8=334

x=334.8

x=2672

Vậy x=2672

293-8.27+x.25=80

77+x.25=80

x.25=80-77

x.25=3

x=3:25

x=\(\frac{3}{25}\)

Vậy x=\(\frac{3}{25}\)

Answer 4

504:[16-3.X]=72 16-3.X=504:72 16-3.X=7 3.X=16-7 3.X=9 X=9:3 X=3

Answer 10

x=3/25 bạn nhé !

Answer 11

a; 504:[16-3.x]=72

16-3.x=504:72=7

3x=16-7=9

x=9:3=3

B,  272-[4.X+15]=45

     4.x+15=272-45=227

    4.x=227-15=212

   x=212:4=53

C,425-x:8=91

x:8=425-91=334

x=334.8=2672

d, 293-8.27+x.25=80

293-216+x.25=80

77+x.25=80

x.25=80-77=3

x=3:25

x=\(\frac{3}{25}\)

Answer 12

504:[16-3x]=72

16-3x=504:72

16-3x=7

3x=16-7

3x=9

x=9:3

x=3

vậy x=3 

câu hai cậu chỉ cần làm gần giông với câu một 

câu ba làm theo thứ tự thục hiện phép tính nhé

293-8.27+x25=80

293-216+x25=80

77+x25=80

x25=80-77

x25=3

x=3:25

x=0,12

vậy x=0,12

Answer 13

16-3x=7

3x=9

x=3

Answer 14

a,504:(16-3.x)=72

           16-3. x=504:72

            16-3 .x =7

                3. x=16-7

               3x=9

                 x=9:3

               x=3

              vậy x=3

Answer 15

đúng rùi

x=3

Answer 18

3/25 nhé

Answer 19

504:[16-3.x]=72

16-3.x=504:72

16-3.x=7

3.x=9

x=3

vậy x=3

272-[4.x+15]=45

4.x+15=272

4.x=212
