Tohaina
Kua tāruatia ki te papatopenga
-65y+19+2y<41
Me tāpiri te 2y ki ngā taha e rua.
-63y+19<41
Pahekotia te -65y me 2y, ka -63y.
-63y<41-19
Tangohia te 19 mai i ngā taha e rua.
-63y<22
Tangohia te 19 i te 41, ka 22.
y>-\frac{22}{63}
Whakawehea ngā taha e rua ki te -63. I te mea he tōraro a -63, ka huri te ahunga koreōrite.
