Question

 x : 0,125 + x : 20% – x : 25% + x + 36,8 = 75,2

Answer 1

=

=>x=3,84

Vậy x =3,84

Answer 2

\(x\div0,125+x\div20\%-x\div25\%+x+36,8=75,2\)

\(10x+36,8=75,2\)

\(10x=75,2-36,8\)

\(10x=38,4\)

   \(x=38,4\div10\)

   \(x=3,84\)

 

Answer 3

x÷0,125+x÷20−x÷25%+x+36,8=75,210x+36,8=75,210x=75,2−36,810x=38,4x=38,4÷10
