Kua tāruatia ki te papatopenga
-5y=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-5y}{-5}=-\frac{x}{-5}
Whakawehea ngā taha e rua ki te -5.
y=-\frac{x}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=\frac{x}{5}
Whakawehe -x ki te -5.
x=5y
Me tāpiri te 5y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
