325x+13=9-y
Tangohia te y mai i ngā taha e rua.
325x=9-y-13
Tangohia te 13 mai i ngā taha e rua.
325x=-4-y
Tangohia te 13 i te 9, ka -4.
325x=-y-4
He hanga arowhānui tō te whārite.
\frac{325x}{325}=\frac{-y-4}{325}
Whakawehea ngā taha e rua ki te 325.
x=\frac{-y-4}{325}
Mā te whakawehe ki te 325 ka wetekia te whakareanga ki te 325.
y+13=9-325x
Tangohia te 325x mai i ngā taha e rua.
y=9-325x-13
Tangohia te 13 mai i ngā taha e rua.
y=-4-325x
Tangohia te 13 i te 9, ka -4.
