Question

tìm x

70 - 5 . ( x - 3 ) = 45

 

Answer 1

70 - 5 . ( x - 3 ) = 45

       5 . ( x - 3 ) = 70 - 45

        5 . ( x - 3 ) = 15

               x - 3   = 15 : 5

               x - 3   = 3

                x        = 3 + 3

                x         = 6

Answer 2

70-5.(x-3)=45

5.(x-3)=70-45

5.(x-3)=25

x-3=25:5

x-3=5

x=5+3

x=8

Answer 3

\(\text{70-5(x-3)=45 5(x-3)=70-45 5(x-3)=25 x-3=25:5 x-3=5 x=5+3 x=8 }\)

Answer 4

70-5.(x-3)=45

     5.(x-3)=70-45=25

         x-3=25:5=5

          x  =5+3

          x   =8
