a, = \(\dfrac{5}{2}.\left(2x-3\right)-\dfrac{1}{2}=\dfrac{11}{3}\)

\(\dfrac{5}{2}.\left(2x-3\right)=\dfrac{11}{3}+\dfrac{1}{2}\)

\(\dfrac{5}{2}.\left(2x-3\right)=\dfrac{25}{6}\)

\(2x-3=\dfrac{25}{6}:\dfrac{5}{2}\)

\(2x-3=\dfrac{5}{3}\)

2x = \(\dfrac{5}{3}+3\)

2x = \(\dfrac{14}{3}\)

x = \(\dfrac{14}{3}:2\)

x = \(\dfrac{7}{3}\)
