Kua tāruatia ki te papatopenga
4x=-7-5y
Tangohia te 5y mai i ngā taha e rua.
4x=-5y-7
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{-5y-7}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{-5y-7}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
5y=-7-4x
Tangohia te 4x mai i ngā taha e rua.
5y=-4x-7
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{-4x-7}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{-4x-7}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
