Question

 Tìm X:

118,24-(X:5 +x nhân 3) =27,12 nhân 2

Answer 1

118,24 - (x:5+x.3)= 54,24

x:5 + x.3 = 118,24 - 54,24 = 64

1/5 x + 15/5 x = 64 

16/5 x = 64 

x = 64 : 16/5 = 20

Answer 2

118,24 - ( x : 5 - x x 3 ) = 27,12 x 2

118,24 - ( x : 5 - x x 3 ) = 54,24

x : 5 - x x 3 = 118,24 - 54,24

x : 5 - x x 3 = 64

1/5x + 15/5x = 64

16/5x = 64

x = 64 : 16/5 = 20 = > x = 20
