Question

Tìm x :

a) X : 5 + 24 = 33

b) 5 + X x 2 = 25

Answer 1

a ) x : 5 + 24 = 33

             x : 5 = 33 - 24

             x : 5 = 9

                 x = 9 x 5

                  x = 45

b ) 5 + X x 2 = 25

               X x 2 = 25 - 5
              X x 2 = 20

                    x = 20 : 2

                     x = 10

Answer 2

a) X : 5 + 24 = 33

X : 5 = 33 - 24

X : 5 = 9

X = 9 x 5

X = 45

b) 5 + X x 2 = 25

X x 2 = 25 - 5

X x 2 = 20

X = 20 : 2

X = 10

Answer 3

X=====x=x=xxxxxxxxxxxxxxx

Answer 4

a) x:5+24=33

x:5=33-24

x:5=9

x=9.5=45

b) 5+x.2=25

x.2=25-5

x.2=20

x=20:2=10

Answer 5

a) X : 5 + 24 = 33

X : 5 = 33 - 24

X : 5 = 9

X = 9 x 5

X = 45

b) 5 + X x 2 = 25

X x 2 = 25 - 5

X x 2 = 20

X = 20 : 2

X = 10

Answer 6

a) X : 5 + 24 = 33

X : 5 = 33 - 24

X : 5 = 9

X = 9 x 5

X = 45

b) 5 + X x 2 = 25

X x 2 = 25 - 5

X x 2 = 20

X = 20 : 2

X = 10
