\(x.\dfrac{-3}{4}=\dfrac{2}{5}+\dfrac{4}{3}\\ x.\dfrac{-3}{4}=\dfrac{31}{15}\\ x=\dfrac{31}{15}:\dfrac{-3}{4}\\ x=\dfrac{-31}{20}\\ 1-1\dfrac{1}{5}x=60\%\\ 1-\dfrac{6}{5}x=\dfrac{3}{5}\\ \dfrac{6}{5}x=1-\dfrac{3}{5}\\ \dfrac{6}{5}x=\dfrac{2}{5}\\ x=\dfrac{2}{5}:\dfrac{6}{5}\\ x=\dfrac{1}{3}\\ \dfrac{1}{2}x+\dfrac{3}{2}x+x=16\\ x.\left(\dfrac{1}{2}+\dfrac{3}{2}+1\right)=16\\ x.3=16\\ x=16:3\\ x=\dfrac{16}{3}\)
