Answer 2

( X + 5 ) + ( X - 5 ) + ( X x 5 ) + ( X : 5 ) = 52

X + 5 + X - 5 + ( X x 5 ) + ( X : 5 ) = 52

( X + X ) + ( 5 - 5 )+ 5X + X/5=52

2X+(5X+X/5)=52

2X=52

X=52/2=26

Answer 3

\(\left(x+5\right)+\left(x-5\right)+\left(x.5\right)+\left(x:5\right)=52\)

\(\Leftrightarrow x+5+x-5+5x+\frac{x}{5}=52\)

\(\Leftrightarrow7x+\frac{x}{5}=52\)

\(\Leftrightarrow x.\left(7+\frac{1}{5}\right)=52\)

\(\Leftrightarrow x.\frac{36}{5}=52\)

\(\Leftrightarrow x=\frac{65}{9}\)

Vậy ...
