Fazemos os cálculos:

$\boxed{\begin{array}{lr} \large \sf y-\dfrac{y-3}{2} =3.(y-1)\\ \\ \large \sf y-\dfrac{y-3}{2}=3y-3 \\ \\ \large \sf 2y-(y-3)=6y-6 \\ \\ \large \sf 2y-y+3)=6y-6 \\ \\ \large \sf y+3=6-6 \\ \\ \large \sf y-6y=-6-3 \\ \\ \large \sf -5y=-9 \\ \\ \large \sf -5y\div(-5)=-9\div(-5)\\ \\ \large \sf y=\dfrac{9}{5} \end{array}}$

Resposta:

$\huge\boxed{\boxed{\sf y=\dfrac{9}{5}}}$

Bons estudos =)
