Kua tāruatia ki te papatopenga
4x=-4-y
Tangohia te y mai i ngā taha e rua.
4x=-y-4
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{-y-4}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{-y-4}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=-\frac{y}{4}-1
Whakawehe -4-y ki te 4.
y=-4-4x
Tangohia te 4x mai i ngā taha e rua.
