Whakaoti mō t
t = \frac{9}{2} = 4\frac{1}{2} = 4.5
Tohaina
Kua tāruatia ki te papatopenga
2t-13+2t=5
Me tāpiri te 2t ki ngā taha e rua.
4t-13=5
Pahekotia te 2t me 2t, ka 4t.
4t=5+13
Me tāpiri te 13 ki ngā taha e rua.
4t=18
Tāpirihia te 5 ki te 13, ka 18.
t=\frac{18}{4}
Whakawehea ngā taha e rua ki te 4.
t=\frac{9}{2}
Whakahekea te hautanga \frac{18}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
