18. ( (2) frac{left[7left(frac{5 x}{3}-frac{3}{2}right)right]}{2}+3 / 2=1 / 4 ) ( Rightarrow quad frac{35 x}{6}-frac{21}{4}+frac{3}{2}=frac{1}{4} ) ( Rightarrow quad frac{35 x}{6}=frac{1}{4}+frac{21}{4}-frac{3}{2} ) ( Rightarrow quad frac{35 x}{6}=frac{1+21-6}{4} ) ( Rightarrow quad x=frac{6}{35} times frac{16}{4}=frac{24}{35} )
