Kua tāruatia ki te papatopenga
-8x-9=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-8x=-2y+9
Me tāpiri te 9 ki ngā taha e rua.
-8x=9-2y
He hanga arowhānui tō te whārite.
\frac{-8x}{-8}=\frac{9-2y}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{9-2y}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
x=\frac{y}{4}-\frac{9}{8}
Whakawehe -2y+9 ki te -8.
2y-9=8x
Me tāpiri te 8x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
2y=8x+9
Me tāpiri te 9 ki ngā taha e rua.
\frac{2y}{2}=\frac{8x+9}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{8x+9}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=4x+\frac{9}{2}
Whakawehe 8x+9 ki te 2.
