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