Whakaoti mō b
b=\frac{4-a}{3}
Whakaoti mō a
a=4-3b
Pātaitai
Algebra
a + 3 b = 4
Tohaina
Kua tāruatia ki te papatopenga
3b=4-a
Tangohia te a mai i ngā taha e rua.
\frac{3b}{3}=\frac{4-a}{3}
Whakawehea ngā taha e rua ki te 3.
b=\frac{4-a}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
a=4-3b
Tangohia te 3b mai i ngā taha e rua.
