Question

tìm X

12,56 x X + X : 0,25 = 69,552

 

Answer 1

12,56 x X + X : 0,25 = 69,552

12,56 x X + X x 4 = 69,552

X x ( 12,56 + 4 ) = 69,552

X x 16,56 = 69,552

X = 69,552 : 16,56

X = 4,2

Answer 2

12 , 56 x X + X : 0 , 25 = 69 , 552 

12 , 56 x X + X x 4       = 69 , 552 

X x ( 12 , 56 + 4 )         = 69 , 552 

X x 16 , 56                   = 69 , 552 

       X                          = 69 , 552  :16 , 56

      X                           =  4 , 2 

 Vậy X = 4 , 2

Answer 3

\(12,56.x+x:0,25=69,552\)

\(x.\left(12,56+4\right)=69,552\)

\(x.16,56=69,552\)

\(x=4,2\)
