\(\frac{x-3}{4}=-\frac{5}{7}\)
\(\Leftrightarrow7\left(x-3\right)=-5\cdot4\)
\(\Leftrightarrow7x-21=-20\)
\(\Leftrightarrow7x=1\)
\(\Leftrightarrow x=\frac{1}{7}\)
\(x-\frac{3}{4}=-\frac{5}{7}\)
\(=>x=-\frac{5}{7}+\frac{3}{4}\)
\(=>x=\frac{1}{28}\)
\(x-\frac{3}{4}=-\frac{5}{7}\)
\(\Rightarrow x=-\frac{5}{7}+\frac{3}{4}\)
\(\Rightarrow x=\frac{1}{28}\)
\(x-\frac{3}{4}=\frac{5}{7}\)
\(\Rightarrow x=\frac{5}{7}+\frac{3}{4}\)
\(\Rightarrow x=\frac{41}{28}\)
\(x-\frac{3}{4}=\frac{-5}{7}\)
\(x=\frac{-5}{7}+\frac{3}{4}\)
\(x=\frac{1}{28}\)
chúc bạn học tốt(nhớ like cho mink)
