Answer 3

\(\frac{3}{x-5}=\frac{-4}{4+2}\)

→  -4 . ( x - 5 ) = 3 . ( 4 + 2)

→ -4x - 20 = 12 + 6

→ -4x - 20 = 18

→ -4x = 18 + 20 = 38

→ x = 38 : ( -4 ) = -9,5

 

Answer 4

\(\frac{3}{x}-5=-\frac{4}{4}+2\)

\(\frac{3}{x}-5=-1+2\)

\(\frac{3}{x}-5=1\)

\(\frac{3}{x}=1+5\)

\(\frac{3}{x}=6\)

\(x=\frac{3}{6}\)

\(x=\frac{1}{2}\)

Answer 5

Trần Việt Hà làm sai r! X= 1/2 ms đúng chứ!
