Kua tāruatia ki te papatopenga
6x-8=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
6x=-2y+8
Me tāpiri te 8 ki ngā taha e rua.
6x=8-2y
He hanga arowhānui tō te whārite.
\frac{6x}{6}=\frac{8-2y}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{8-2y}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=\frac{4-y}{3}
Whakawehe -2y+8 ki te 6.
2y-8=-6x
Tangohia te 6x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2y=-6x+8
Me tāpiri te 8 ki ngā taha e rua.
2y=8-6x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{8-6x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{8-6x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=4-3x
Whakawehe -6x+8 ki te 2.
