Kua tāruatia ki te papatopenga
3x-13=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
3x=-2y+13
Me tāpiri te 13 ki ngā taha e rua.
3x=13-2y
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{13-2y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{13-2y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2y-13=-3x
Tangohia te 3x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2y=-3x+13
Me tāpiri te 13 ki ngā taha e rua.
2y=13-3x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{13-3x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{13-3x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
