Kua tāruatia ki te papatopenga
5x-8=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5x=-2y+8
Me tāpiri te 8 ki ngā taha e rua.
5x=8-2y
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{8-2y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{8-2y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
2y-8=-5x
Tangohia te 5x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2y=-5x+8
Me tāpiri te 8 ki ngā taha e rua.
2y=8-5x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{8-5x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{8-5x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{5x}{2}+4
Whakawehe -5x+8 ki te 2.
