Kua tāruatia ki te papatopenga
40x=10y
Me tāpiri te 10y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{40x}{40}=\frac{10y}{40}
Whakawehea ngā taha e rua ki te 40.
x=\frac{10y}{40}
Mā te whakawehe ki te 40 ka wetekia te whakareanga ki te 40.
x=\frac{y}{4}
Whakawehe 10y ki te 40.
-10y=-40x
Tangohia te 40x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-10y}{-10}=-\frac{40x}{-10}
Whakawehea ngā taha e rua ki te -10.
y=-\frac{40x}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
y=4x
Whakawehe -40x ki te -10.
