Kua tāruatia ki te papatopenga
4x=-12+2y
Me tāpiri te 2y ki ngā taha e rua.
4x=2y-12
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{2y-12}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{2y-12}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{y}{2}-3
Whakawehe -12+2y ki te 4.
-2y=-12-4x
Tangohia te 4x mai i ngā taha e rua.
-2y=-4x-12
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{-4x-12}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-4x-12}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=2x+6
Whakawehe -12-4x ki te -2.
