Answer 2

$\mathsf{Given :\;4 - \dfrac{2(z - 4)}{3} = \dfrac{1}{2}(2z + 5)}$

$\mathsf{\implies \dfrac{3(4) - 2(z - 4)}{3} = \dfrac{(2z + 5)}{2}}$

$\mathsf{\implies \dfrac{12 - 2z + 8}{3} = \dfrac{2z + 5}{2}}$

$\mathsf{\implies \dfrac{20 - 2z}{3} = \dfrac{2z + 5}{2}}$

$\mathsf{\implies {2(20 - 2z)} = {3(2z + 5)}}$

$\mathsf{\implies {40 - 4z} = {6z + 15}}$

$\mathsf{\implies {6z + 4z} = {40 - 15}}$

$\mathsf{\implies {10z} = {25}}$

$\mathsf{\implies {z} = \dfrac{25}{10}}$

$\mathsf{\implies {z} = \dfrac{5}{2}}$
