Kua tāruatia ki te papatopenga
x-3+5x=18
Me tāpiri te 5x ki ngā taha e rua.
6x-3=18
Pahekotia te x me 5x, ka 6x.
6x=18+3
Me tāpiri te 3 ki ngā taha e rua.
6x=21
Tāpirihia te 18 ki te 3, ka 21.
x=\frac{21}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{7}{2}
Whakahekea te hautanga \frac{21}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
