Whakaoti mō n
n = \frac{5}{2} = 2\frac{1}{2} = 2.5
Tohaina
Kua tāruatia ki te papatopenga
-2n=16-21
Tangohia te 21 mai i ngā taha e rua.
-2n=-5
Tangohia te 21 i te 16, ka -5.
n=\frac{-5}{-2}
Whakawehea ngā taha e rua ki te -2.
n=\frac{5}{2}
Ka taea te hautanga \frac{-5}{-2} te whakamāmā ki te \frac{5}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
