6x=-15-3y
Tangohia te 3y mai i ngā taha e rua.
6x=-3y-15
He hanga arowhānui tō te whārite.
\frac{6x}{6}=\frac{-3y-15}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{-3y-15}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=\frac{-y-5}{2}
Whakawehe -15-3y ki te 6.
3y=-15-6x
Tangohia te 6x mai i ngā taha e rua.
3y=-6x-15
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{-6x-15}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{-6x-15}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-2x-5
Whakawehe -15-6x ki te 3.
