7. (2x - 3) = 133

2x - 3 = 133 : 7

2x - 3 = 19

2x = 19 + 3

2x = 22

x = 22 : 2 

x= 11

7.(2x-3)=133

14x-21=133

14x=133+21

14x=154

x=154:14

x=11

Vậy x=11

Giúp e câu này vs ạ

Olm chào em, bài này thì em làm như sau em nhé:

                               79 - 66,8 12,2

5,28 12,5 x 2640 1056 528 66,000

a, M = 1,11 + 1,12 + 1,13 + ... + 1,49 + 1,50

Dãy số trên là dãy số cách đều với  khoảng cách là:

           1,11 - 1,11 = 0,01

Số số hạng của dãy số trên là:

     (1,50 - 1,11): 0,01 + 1  = 40

   M = (1,50 + 1,11) x 40 : 2  = 52,2

a,      M = 1,11 + 1,12 + 1,13 +... + 1,50 

Dãy số trên là dãy số cách đều với khoảng là:

          1,12 - 1,11 = 0,01

Số số hạng của dãy số trên là: 

     (1,50 - 1,11): 0,01 + 1  = 40

M =  (1,50 + 1,11) x 40 : 2 = 52,2
