Whakaoti mō k
k=-\frac{b}{45}+\frac{7}{9}
Whakaoti mō b
b=35-45k
Tohaina
Kua tāruatia ki te papatopenga
45k=35-b
Tangohia te b mai i ngā taha e rua.
\frac{45k}{45}=\frac{35-b}{45}
Whakawehea ngā taha e rua ki te 45.
k=\frac{35-b}{45}
Mā te whakawehe ki te 45 ka wetekia te whakareanga ki te 45.
k=-\frac{b}{45}+\frac{7}{9}
Whakawehe 35-b ki te 45.
b=35-45k
Tangohia te 45k mai i ngā taha e rua.
