20) \(2x-\dfrac{2}{3}-7x=\dfrac{3}{2}-1\)
22) \(-\dfrac{5}{3}x=\dfrac{7}{10}x+\dfrac{5}{6}\)
23) \(2x-\dfrac{1}{4}=\dfrac{5}{6}-\dfrac{1}{2}x\)
24) \(\dfrac{5}{6}+3x=\dfrac{2}{3}-\dfrac{1}{2}x\)
25) \(3x-\dfrac{5}{3}=x+\dfrac{1}{4}\) 
26) \(3.\left(x-\dfrac{1}{2}\right)-3\left(x-\dfrac{1}{3}\right)=x\)
27) \(\left(x+2\right)-4\left(x-\dfrac{1}{4}\right)=\dfrac{1}{2}x\)
