Question

 Tìm X :

14 x X + 25 x X - 13 x X = 52

 

Answer 1

14 x X + 25 x X - 13 x X = 52

X x ( 14 + 25 - 13 ) = 52

X x 26 = 52

       X  = 52 : 26

       X  =    2   

Answer 2

X x (14 + 25 - 13) = 52 

X x 26 = 52

X = 52 : 26 

X = 2

Answer 3

14 x X + 25 x X- 13 x X=52

X x ( 14+25-13) =52

X x 26=52

X=52:26

X=2

Answer 4

\(14\times x+25\times x-13\times x=52\)

\(\implies x\times (14+25-13)=52\)

\(\implies x \times 26=52\)

\(\implies x=52:26\)

\(\implies x=2\)

Vậy x=2.
