Kua tāruatia ki te papatopenga
4x+y=-8
Tangohia te 8 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4x=-8-y
Tangohia te y mai i ngā taha e rua.
4x=-y-8
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{-y-8}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{-y-8}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=-\frac{y}{4}-2
Whakawehe -8-y ki te 4.
8+y=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
y=-4x-8
Tangohia te 8 mai i ngā taha e rua.
