Kua tāruatia ki te papatopenga
-9x=y-9y
Tangohia te 9y mai i ngā taha e rua.
-9x=-8y
Pahekotia te y me -9y, ka -8y.
\frac{-9x}{-9}=-\frac{8y}{-9}
Whakawehea ngā taha e rua ki te -9.
x=-\frac{8y}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
x=\frac{8y}{9}
Whakawehe -8y ki te -9.
9y-9x-y=0
Tangohia te y mai i ngā taha e rua.
8y-9x=0
Pahekotia te 9y me -y, ka 8y.
8y=9x
Me tāpiri te 9x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{8y}{8}=\frac{9x}{8}
Whakawehea ngā taha e rua ki te 8.
y=\frac{9x}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
