Whakaoti mō t
t = \frac{18}{5} = 3\frac{3}{5} = 3.6
Tohaina
Kua tāruatia ki te papatopenga
-5t=7-25
Tangohia te 25 mai i ngā taha e rua.
-5t=-18
Tangohia te 25 i te 7, ka -18.
t=\frac{-18}{-5}
Whakawehea ngā taha e rua ki te -5.
t=\frac{18}{5}
Ka taea te hautanga \frac{-18}{-5} te whakamāmā ki te \frac{18}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
