Kua tāruatia ki te papatopenga
4y=-64-x
Tangohia te x mai i ngā taha e rua.
4y=-x-64
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{-x-64}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{-x-64}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{x}{4}-16
Whakawehe -64-x ki te 4.
x=-64-4y
Tangohia te 4y mai i ngā taha e rua.
