Kua tāruatia ki te papatopenga
15x-7+12x=11
Me tāpiri te 12x ki ngā taha e rua.
27x-7=11
Pahekotia te 15x me 12x, ka 27x.
27x=11+7
Me tāpiri te 7 ki ngā taha e rua.
27x=18
Tāpirihia te 11 ki te 7, ka 18.
x=\frac{18}{27}
Whakawehea ngā taha e rua ki te 27.
x=\frac{2}{3}
Whakahekea te hautanga \frac{18}{27} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.
