Kua tāruatia ki te papatopenga
-4x=-8-2y
Tangohia te 2y mai i ngā taha e rua.
-4x=-2y-8
He hanga arowhānui tō te whārite.
\frac{-4x}{-4}=\frac{-2y-8}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{-2y-8}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{y}{2}+2
Whakawehe -8-2y ki te -4.
2y=-8+4x
Me tāpiri te 4x ki ngā taha e rua.
2y=4x-8
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{4x-8}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{4x-8}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=2x-4
Whakawehe -8+4x ki te 2.
