12x=-78-4y
Tangohia te 4y mai i ngā taha e rua.
12x=-4y-78
He hanga arowhānui tō te whārite.
\frac{12x}{12}=\frac{-4y-78}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{-4y-78}{12}
Mā te whakawehe ki te 12 ka wetekia te whakareanga ki te 12.
x=-\frac{y}{3}-\frac{13}{2}
Whakawehe -78-4y ki te 12.
4y=-78-12x
Tangohia te 12x mai i ngā taha e rua.
4y=-12x-78
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{-12x-78}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{-12x-78}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-3x-\frac{39}{2}
Whakawehe -78-12x ki te 4.
