Whakaoti mō a
a=\frac{b+4}{3}
Whakaoti mō b
b=3a-4
Tohaina
Kua tāruatia ki te papatopenga
3a-1=b+3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3a=b+3+1
Me tāpiri te 1 ki ngā taha e rua.
3a=b+4
Tāpirihia te 3 ki te 1, ka 4.
\frac{3a}{3}=\frac{b+4}{3}
Whakawehea ngā taha e rua ki te 3.
a=\frac{b+4}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
b=3a-1-3
Tangohia te 3 mai i ngā taha e rua.
b=3a-4
Tangohia te 3 i te -1, ka -4.
