Tohaina
Kua tāruatia ki te papatopenga
11a+4b=28
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
11a=28-4b
Tangohia te 4b mai i ngā taha e rua.
\frac{11a}{11}=\frac{28-4b}{11}
Whakawehea ngā taha e rua ki te 11.
a=\frac{28-4b}{11}
Mā te whakawehe ki te 11 ka wetekia te whakareanga ki te 11.
11a+4b=28
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4b=28-11a
Tangohia te 11a mai i ngā taha e rua.
\frac{4b}{4}=\frac{28-11a}{4}
Whakawehea ngā taha e rua ki te 4.
b=\frac{28-11a}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
b=-\frac{11a}{4}+7
Whakawehe 28-11a ki te 4.
