Whakaoti mō V_19
V_{19}=1815
Pātaitai
Linear Equation
5 raruraru e ōrite ana ki:
10 = V19- \frac{ 1 }{ 2 } \times 10 \times { 19 }^{ 2 }
Tohaina
Kua tāruatia ki te papatopenga
10=V_{19}-\frac{10}{2}\times 19^{2}
Whakareatia te \frac{1}{2} ki te 10, ka \frac{10}{2}.
10=V_{19}-5\times 19^{2}
Whakawehea te 10 ki te 2, kia riro ko 5.
10=V_{19}-5\times 361
Tātaihia te 19 mā te pū o 2, kia riro ko 361.
10=V_{19}-1805
Whakareatia te 5 ki te 361, ka 1805.
V_{19}-1805=10
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
V_{19}=10+1805
Me tāpiri te 1805 ki ngā taha e rua.
V_{19}=1815
Tāpirihia te 10 ki te 1805, ka 1815.
