Question

123-(x-7)=1224:12

 

Answer 1

123 - ( x - 7 ) = 1224 : 12

=> 123 - ( x - 7 ) = 102

=>            x - 7   =  123 - 102

=>             x - 7  = 21

=>             x       = 21 + 7

=>              x       = 28

Answer 2

123-(x-7)=1224:12

<=>123-(x-7)=102

<=>x-7=21

<=>x=28

Answer 3

123 - ( x - 7 ) = 1224 : 12

123 - ( x - 7 ) = 102

        ( x - 7 ) = 123 - 102

        ( x - 7 ) = 21

          x        = 21 + 7

          x        = 28

Answer 4

123-(x-7)=1224:12

<=>123-(x-7)=102

<=>x-7=21

<=>x=28

Answer 5

123-(x-7)=1224:12

123-(x-7)=102

(x-7)=123-102

(x-7)=21

x=21+7

x=28

Answer 6

123-(x-7)=1224:12

123-(x-7)=102

(x-7)=123-102

(x-7)=21

x=21+7

x=28
