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