Answer:
y = [tex]\frac{2}{9}[/tex]
Step-by-step explanation:
multiply [tex]\frac{2}{3}[/tex] by [tex]\frac{3}{3}[/tex] to get [tex]\frac{6}{9}[/tex]:
[tex]\frac{6}{9}[/tex] + y - [tex]\frac{1}{9}[/tex] = [tex]\frac{7}{9}[/tex]
simplify:
y + [tex]\frac{5}{9}[/tex] = [tex]\frac{7}{9}[/tex]
subract [tex]\frac{5}{9}[/tex] from both sides:
y = [tex]\frac{2}{9}[/tex]
