Question

\(0,5.x+x:4.6+x:2.4=8\)

 

tìm x  ( dấu chấm là đấu nhân)

Answer 1

\(0,5.x+x:4.6+x:2.4=8\)

\(\Leftrightarrow0,5.x+x.0,25.6+x.0,5.4=8\)

\(\Leftrightarrow x\left(0,5+1,5+2\right)=8\)

\(\Leftrightarrow x.4=8\)

\(\Leftrightarrow x=2\)

Vậy x = 2

Answer 2

0,5 . x + x : 4 . 6 + x : 2 . 4

0,5 . x + x . 0,25 . 6 + x . 0,5 x 4 = 8

0,5.x + x.1,5 + x.2 = 8

x. ( 0,5 + 1,5 + 2 ) = 8

x . 4 = 8

=> x = 2

Answer 3

\(0,5.x+x:4.6+x:2.4=8\)

\(\frac{1}{2}.x+x:24+x:8=8\)

\(\frac{1}{2}.x+x.\frac{1}{24}+x.\frac{1}{8}=8\)

\(x.\left(\frac{1}{2}+\frac{1}{24}+\frac{1}{8}\right)=8\)

\(x.\frac{2}{3}=8\)

\(x=8:\frac{2}{3}\)

\(x=12\)

Answer 4

x=2 . nha
