Kua tāruatia ki te papatopenga
20.2x=172-x
Pahekotia te 15.2x me 5x, ka 20.2x.
20.2x+x=172
Me tāpiri te x ki ngā taha e rua.
21.2x=172
Pahekotia te 20.2x me x, ka 21.2x.
x=\frac{172}{21.2}
Whakawehea ngā taha e rua ki te 21.2.
x=\frac{1720}{212}
Whakarohaina te \frac{172}{21.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{430}{53}
Whakahekea te hautanga \frac{1720}{212} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
