Question

\(\left(\frac{3}{5}x-\frac{2}{3}x-x\right).\frac{1}{7}=\frac{-5}{21}\)

Answer 1

\(\left(\frac{3}{5}.x-\frac{2}{3}.x-x\right).\frac{1}{7}=\frac{-5}{21}\)

\(\Rightarrow x.\left(\frac{3}{5}-\frac{2}{3}-1\right).\frac{1}{7}=\frac{-5}{21}\)

\(\Rightarrow x.\frac{-16}{105}=\frac{-5}{21}\)

\(\Rightarrow x=\frac{-5}{21}:\frac{-16}{105}\)

\(\Rightarrow x=\frac{25}{16}\)

Answer 2

x.[3/5-2/3-1]=-5/21:1/7

x.-16/15=-5/3

x=-5/3:-16/15

x=25/16
