Question

tìm x biết:

x*11,8+x*9,1=100,8

Answer 1

\(x.11,8+x.9,1=100,8\)

\(\Rightarrow x\left(11,8+9,1\right)=100,8\)

\(\Rightarrow x.20,9=100,8\)

\(\Rightarrow x=\frac{1008}{209}\)

Answer 2

x*11,8+x*9,1=100,8

=>x*(11,8+9,1)=100,8

=>x*20,9=100,8

=>x=100,8:20,9

=>x=\(\frac{1008}{209}\)

Vậy x=............

Answer 3

\(x.11,8+x.9,1=100,8\)

\(x.\left(11,8+9,1\right)=100,8\)

\(x.20,9=100,8\)

\(x=\frac{1008}{209}\)

Answer 4

x . 11,8 + x . 9,1 = 100,8

x ( 11,8 + 9,1 ) = 100,8

x . 20,9 = 100,8

x = 100,8 : 20,9

x = \(\frac{1008}{209}\)
