Question

Tìm x :

70-5(x-3)=45

(nêu cách làm luôn nhé )

Answer 1

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 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=2

Answer 3

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
