\(0,5.x+x:4.6+x:2.4=8\)
\(\Leftrightarrow0,5.x+x.0,25.6+x.0,5.4=8\)
\(\Leftrightarrow x\left(0,5+1,5+2\right)=8\)
\(\Leftrightarrow x.4=8\)
\(\Leftrightarrow x=2\)
Vậy x = 2
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
\(0,5.x+x:4.6+x:2.4=8\)
\(\frac{1}{2}.x+x:24+x:8=8\)
\(\frac{1}{2}.x+x.\frac{1}{24}+x.\frac{1}{8}=8\)
\(x.\left(\frac{1}{2}+\frac{1}{24}+\frac{1}{8}\right)=8\)
\(x.\frac{2}{3}=8\)
\(x=8:\frac{2}{3}\)
\(x=12\)
