Kua tāruatia ki te papatopenga
9y-\left(11y-2\right)=0
Whakareatia ngā taha e rua o te whārite ki te 9.
9y-11y-\left(-2\right)=0
Hei kimi i te tauaro o 11y-2, kimihia te tauaro o ia taurangi.
9y-11y+2=0
Ko te tauaro o -2 ko 2.
-2y+2=0
Pahekotia te 9y me -11y, ka -2y.
-2y=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
y=\frac{-2}{-2}
Whakawehea ngā taha e rua ki te -2.
y=1
Whakawehea te -2 ki te -2, kia riro ko 1.
