Tohaina
Kua tāruatia ki te papatopenga
x-y=5.5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=5.5+y
Me tāpiri te y ki ngā taha e rua.
x-y=5.5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-y=5.5-x
Tangohia te x mai i ngā taha e rua.
\frac{-y}{-1}=\frac{5.5-x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{5.5-x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=x-5.5
Whakawehe 5.5-x ki te -1.
