Kua tāruatia ki te papatopenga
7x=-8-5y
Tangohia te 5y mai i ngā taha e rua.
7x=-5y-8
He hanga arowhānui tō te whārite.
\frac{7x}{7}=\frac{-5y-8}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{-5y-8}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
5y=-8-7x
Tangohia te 7x mai i ngā taha e rua.
5y=-7x-8
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{-7x-8}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{-7x-8}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
