Whakaoti mō x
x = -\frac{19}{2} = -9\frac{1}{2} = -9.5
Whakaoti mō y
y = \frac{19}{2} = 9\frac{1}{2} = 9.5

Kua tāruatia ki te papatopenga
2x+19=2y
Me tāpiri te 2y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
2x=2y-19
Tangohia te 19 mai i ngā taha e rua.
\frac{2x}{2}=\frac{2y-19}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{2y-19}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=y-\frac{19}{2}
Whakawehe 2y-19 ki te 2.
-2y+19=-2x
Tangohia te 2x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-2y=-2x-19
Tangohia te 19 mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{-2x-19}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-2x-19}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=x+\frac{19}{2}
Whakawehe -2x-19 ki te -2.
