$\frac{3}{5}$ – x = $\frac{5}{7}$ x = $\frac{3}{5}$ – $\frac{5}{7}$ x = $\frac{-4}{35}$ $\frac{3}{4}$ -2 . ( x -9 ) =$\frac{1}{4}$ -2 . ( x-9 ) = $\frac{3}{4}$ -$\frac{1}{4}$ -2 . ( x-9 ) = $\frac{1}{2}$ x – 9 = $\frac{1}{2}$ : (-2 ) x = $\frac{-1}{4}$ + 9 x = $\frac{-35}{4}$ $\frac{5}{7}$ – $\frac{5}{2}$ : (x-3) = 1 $\frac{5}{2}$ : (x-3)= $\frac{5}{7}$ – 1 $\frac{5}{2}$ : (x-3)= $\frac{-2}{7}$ x – 3=$\frac{-2}{7}$ x $\frac{5}{2}$ x – 3 = $\frac{-5}{7}$ x = $\frac{-5}{7}$ + 3 x = $\frac{16}{7}$ Trả lời
