Kua tāruatia ki te papatopenga
16.2x=172-x
Pahekotia te 15.2x me x, ka 16.2x.
16.2x+x=172
Me tāpiri te x ki ngā taha e rua.
17.2x=172
Pahekotia te 16.2x me x, ka 17.2x.
x=\frac{172}{17.2}
Whakawehea ngā taha e rua ki te 17.2.
x=\frac{1720}{172}
Whakarohaina te \frac{172}{17.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=10
Whakawehea te 1720 ki te 172, kia riro ko 10.
