10=V_{19}-\frac{10}{2}\times 19^{2}
Multiply \frac{1}{2} and 10 to get \frac{10}{2}.
10=V_{19}-5\times 19^{2}
Divide 10 by 2 to get 5.
10=V_{19}-5\times 361
Calculate 19 to the power of 2 and get 361.
10=V_{19}-1805
Multiply 5 and 361 to get 1805.
V_{19}-1805=10
Swap sides so that all variable terms are on the left hand side.
V_{19}=10+1805
Add 1805 to both sides.
V_{19}=1815
Add 10 and 1805 to get 1815.
