Kua tāruatia ki te papatopenga
1x+4y-5=0
Whakawehea te 3 ki te 3, kia riro ko 1.
1x-5=-4y
Tangohia te 4y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
1x=-4y+5
Me tāpiri te 5 ki ngā taha e rua.
x=-4y+5
Whakaraupapatia anō ngā kīanga tau.
1x+4y-5=0
Whakawehea te 3 ki te 3, kia riro ko 1.
4y-5=-x
Tangohia te 1x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4y=-x+5
Me tāpiri te 5 ki ngā taha e rua.
4y=5-x
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{5-x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{5-x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
