Question

440 + 2 . ( 125 - x ) = 546

tìm x

Answer 1

440 + 2 . ( 125 - x ) = 546

2 . ( 125 - x ) = 546 - 440

2 . ( 125 - x ) = 106

125 - x = 106 : 2

125 - x = 53

x = 125 - 53

x = 72

Vậy x = 72

Answer 2

440 + 2. ( 125 - x ) = 546

2 ( 125 - x ) = 546 - 440

2 ( 125 - x ) = 106

125 - x = 106 ÷ 2

125 - x = 53

x = 125 - 53

x = 72

Answer 3

2.(125-x)=546-440

2.(125-x)= 106

(125-x)= 106: 2

(125-x)=53

x=125-53

x=72

Answer 4

440+2.(125-x)=546

2.(125-x)=546-440

2.(125-x)=106

125-x=106/2

125-x=53

x=125-53

x=72

Answer 5

440 + 2 (125 - x ) = 546

         2 (125 - x ) = 546 - 440

         2 (125 - x ) = 106

              125 - x = 106 : 2

             125 - x = 53

                    x = 125 - 53

                   x = 72

Answer 6

440+2. (125-x)= 546

2. (125-x)=  546- 440

2. (125-x)= 106

125- x=  106:2

125- x= 53

         x= 125-53

          x= 72
