Kua tāruatia ki te papatopenga
50x-900+5x=2400
Me tāpiri te 5x ki ngā taha e rua.
55x-900=2400
Pahekotia te 50x me 5x, ka 55x.
55x=2400+900
Me tāpiri te 900 ki ngā taha e rua.
55x=3300
Tāpirihia te 2400 ki te 900, ka 3300.
x=\frac{3300}{55}
Whakawehea ngā taha e rua ki te 55.
x=60
Whakawehea te 3300 ki te 55, kia riro ko 60.
