Ta có : \(\frac{x-3}{4}=\frac{-4}{8}\)
\(\Rightarrow8x-24=-16\)
\(\Rightarrow8x=-16+24=8\)
\(\Rightarrow x=1\)
\(\frac{x-3}{4}=\frac{-4}{8}\)
\(\Rightarrow-4\cdot4=\left(x-3\right)\cdot8\)
\(\Rightarrow-16=8x-24\)
\(\Rightarrow-16+24=8x\)
\(\Rightarrow8=8x\)
\(\Rightarrow x=1\)
\(x-\frac{3}{4}=\frac{-4}{8}\)
x=1/4
