![= { \frac{9y}{9y} \cdot \frac{y + [ \frac{(y - 3)}{3}]}{(\frac{5}{9} + \frac{2}{3y})}}\\\\= { \frac{y \cdot 9y + y\cdot 9y- \frac{3}{3}]} { 9y(\frac{5}{9}) + 9y(\frac{2}{3y})}}\\\\={ \frac{y \cdot 9y + 3y(y-3)} { 9y(\frac{5}{9}) + 9y(\frac{2}{3y})}}\\\\={ \frac{y \cdot 9y + 3y(y-3)} { y \cdot 5 + 9y(\frac{2}{3y})}}\\\\={ \frac{9y^2 + 3y^2-9y} { 5y + 6}}\\\\={ \frac{12y^2 -9y} { 5y + 6}}\\\\](/tpl/images/0519/7477/ee300.png)
