\{ ( 2 y - 0.3 ) = 194 - y
Whakaoti mō y
y = \frac{1943}{30} = 64\frac{23}{30} \approx 64.766666667

Kua tāruatia ki te papatopenga
2y-0.3+y=194
Me tāpiri te y ki ngā taha e rua.
3y-0.3=194
Pahekotia te 2y me y, ka 3y.
3y=194+0.3
Me tāpiri te 0.3 ki ngā taha e rua.
3y=194.3
Tāpirihia te 194 ki te 0.3, ka 194.3.
y=\frac{194.3}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{1943}{30}
Whakarohaina te \frac{194.3}{3} mā te whakarea i te taurunga me te tauraro ki te 10.
