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