Kua tāruatia ki te papatopenga
\frac{14m}{5}k=300m
He hanga arowhānui tō te whārite.
\frac{5\times \frac{14m}{5}k}{14m}=\frac{5\times 300m}{14m}
Whakawehea ngā taha e rua ki te 2.8m.
k=\frac{5\times 300m}{14m}
Mā te whakawehe ki te 2.8m ka wetekia te whakareanga ki te 2.8m.
k=\frac{750}{7}
Whakawehe 300m ki te 2.8m.
2.8km-300m=0
Tangohia te 300m mai i ngā taha e rua.
\left(2.8k-300\right)m=0
Pahekotia ngā kīanga tau katoa e whai ana i te m.
\left(\frac{14k}{5}-300\right)m=0
He hanga arowhānui tō te whārite.
m=0
Whakawehe 0 ki te -300+2.8k.
