Question

\(\frac{-8}{3x-1}\)=\(\frac{4}{-7}\)

Answer 1

\(\frac{-8}{3x-1}=\frac{4}{-7}\)

\(\Rightarrow\left(-8\right).\left(-7\right)=4.\left(3x-1\right)\)

\(\Rightarrow56=12x-4\)

\(\Rightarrow56+4=12x\)

\(\Rightarrow12x=60\)

\(\Rightarrow x=5\)

Answer 2

\(\Rightarrow x=5\)

Answer 3

\(\frac{-8}{3x-1}=\frac{4}{-7}\)

\(\Rightarrow-8.\left(-7\right)=3x-1.4\)

\(\Rightarrow56=3x-4\)

\(\Rightarrow3x=-4-56\)

\(\Rightarrow3x=-60\)

\(\Rightarrow x=-60:3\)

\(\Rightarrow x=-20\)

Answer 4
