Kua tāruatia ki te papatopenga
2x=14+9y
Me tāpiri te 9y ki ngā taha e rua.
2x=9y+14
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{9y+14}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{9y+14}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{9y}{2}+7
Whakawehe 14+9y ki te 2.
-9y=14-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-9y}{-9}=\frac{14-2x}{-9}
Whakawehea ngā taha e rua ki te -9.
y=\frac{14-2x}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
y=\frac{2x-14}{9}
Whakawehe 14-2x ki te -9.
