Kua tāruatia ki te papatopenga
-\frac{1}{9}y=\left(-12\right)^{-1}
Tātaihia te -9 mā te pū o -1, kia riro ko -\frac{1}{9}.
-\frac{1}{9}y=-\frac{1}{12}
Tātaihia te -12 mā te pū o -1, kia riro ko -\frac{1}{12}.
y=-\frac{1}{12}\left(-9\right)
Me whakarea ngā taha e rua ki te -9, te tau utu o -\frac{1}{9}.
y=\frac{3}{4}
Whakareatia te -\frac{1}{12} ki te -9, ka \frac{3}{4}.
