Kua tāruatia ki te papatopenga
x+y-10x=0
Tangohia te 10x mai i ngā taha e rua.
-9x+y=0
Pahekotia te x me -10x, ka -9x.
-9x=-y
Tangohia te y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-9x}{-9}=-\frac{y}{-9}
Whakawehea ngā taha e rua ki te -9.
x=-\frac{y}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
x=\frac{y}{9}
Whakawehe -y ki te -9.
y=10x-x
Tangohia te x mai i ngā taha e rua.
y=9x
Pahekotia te 10x me -x, ka 9x.
