Question

Tìm số x biết :

10+20+30=(120:(x-6)+24)

Answer 1

Lớp 6 rồi mà gà quá :v

Ta có:

10+20+30=(120:(x-6)+24)

=>(120:(x-6)+24)=60

=> 120:(x-6)=36

=> x-6=10/3

=> x=28/3

Answer 2

Ta có :

10 + 20 = 30 = [ 120 : ( x - 6 ) + 24 ]

Suy ra [ 120 : ( x - 6 ) + 24 ] = 60

Suy ra 120 : ( x - 6 ) = 36

Suy ra x - 6 = 10/3

Suy ra x = 28/3

Answer 3

10 + 20 + 30 = (120 : (x - 6) + 24)

60 = (120 : (x - 6) + 24)

=> (120 : (x - 6) + 24) = 60 

120 : x - 6 = 60 - 24 

120 : x - 6 = 36 

x - 6 = 120 : 36 

x - 6 = \(\frac{10}{3}\)

x = \(\frac{10}{3}+6\)

x = \(\frac{10}{3}+\frac{6}{1}=\frac{10}{3}+\frac{18}{3}\)

=> x = \(\frac{28}{3}\)
