Tohaina
Kua tāruatia ki te papatopenga
-4x-7=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-4x=y+7
Me tāpiri te 7 ki ngā taha e rua.
\frac{-4x}{-4}=\frac{y+7}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{y+7}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{-y-7}{4}
Whakawehe y+7 ki te -4.
