Tìm x? 

Ai biết làm thì giúp mình với ạ ,mình đang cần gấp .😥

Answer 1

       \(\frac{x+5}{3}=\frac{x-1}{4}\)

\(\Rightarrow\left(x+5\right).4=\left(x-1\right).3\)

\(\Rightarrow4x+20=3x-3\)

\(\Rightarrow4x-3x=-3-20\Rightarrow x=-23\)

Answer 2

\(\frac{x+5}{3}=\frac{x-1}{4}\)

\(\Rightarrow\left(x+5\right)\cdot4=\left(x-1\right)\cdot3\)

\(4x+20=3x-3\)

\(4x-3x=-3-20\)

\(x=-23\)

Vậy \(x=-23\)
