Kua tāruatia ki te papatopenga
-x-7=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=y+7
Me tāpiri te 7 ki ngā taha e rua.
\frac{-x}{-1}=\frac{y+7}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{y+7}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=-\left(y+7\right)
Whakawehe y+7 ki te -1.
