Kua tāruatia ki te papatopenga
15x=-15+2y
Me tāpiri te 2y ki ngā taha e rua.
15x=2y-15
He hanga arowhānui tō te whārite.
\frac{15x}{15}=\frac{2y-15}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{2y-15}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
x=\frac{2y}{15}-1
Whakawehe -15+2y ki te 15.
-2y=-15-15x
Tangohia te 15x mai i ngā taha e rua.
-2y=-15x-15
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{-15x-15}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-15x-15}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{15x+15}{2}
Whakawehe -15-15x ki te -2.
