Kua tāruatia ki te papatopenga
3x=-4-2y
Tangohia te 2y mai i ngā taha e rua.
3x=-2y-4
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{-2y-4}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{-2y-4}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2y=-4-3x
Tangohia te 3x mai i ngā taha e rua.
2y=-3x-4
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{-3x-4}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{-3x-4}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{3x}{2}-2
Whakawehe -4-3x ki te 2.
