Whakaoti mō y
y=\frac{z}{3}
Whakaoti mō z
z=3y
Tohaina
Kua tāruatia ki te papatopenga
-3y=-z
Tangohia te z mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{-3y}{-3}=-\frac{z}{-3}
Whakawehea ngā taha e rua ki te -3.
y=-\frac{z}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{z}{3}
Whakawehe -z ki te -3.
z=3y
Me tāpiri te 3y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
