Answer:
[tex]\sf 1\frac{1}{6}[/tex]
solving steps:
[tex]\sf given: x = 9, \ y = \frac{5}{6}[/tex]
solve:
[tex]\sf \frac{2}{3} (x-6)-y[/tex]
[tex]\sf \frac{2}{3} (9-6)-\frac{5}{6}[/tex]
[tex]\sf \frac{2}{3} (3)-\frac{5}{6}[/tex]
[tex]\sf 2 - \frac{5}{6}[/tex]
[tex]\sf \frac{12}{6} -\frac{5}{6}[/tex]
[tex]\sf \frac{12-5}{6}[/tex]
[tex]\sf \frac{7}{6}[/tex]
[tex]\sf 1\frac{1}{6}[/tex]
