Whakaoti mō k
k=\frac{n-2}{2}
Whakaoti mō n
n=2\left(k+1\right)
Tohaina
Kua tāruatia ki te papatopenga
-2k=2-n
Tangohia te n mai i ngā taha e rua.
\frac{-2k}{-2}=\frac{2-n}{-2}
Whakawehea ngā taha e rua ki te -2.
k=\frac{2-n}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
k=\frac{n}{2}-1
Whakawehe 2-n ki te -2.
n=2+2k
Me tāpiri te 2k ki ngā taha e rua.
