-640t+500=-7k^{2}
Subtract 7k^{2} from both sides. Anything subtracted from zero gives its negation.
-640t=-7k^{2}-500
Subtract 500 from both sides.
\frac{-640t}{-640}=\frac{-7k^{2}-500}{-640}
Divide both sides by -640.
t=\frac{-7k^{2}-500}{-640}
Dividing by -640 undoes the multiplication by -640.
t=\frac{7k^{2}}{640}+\frac{25}{32}
Divide -7k^{2}-500 by -640.
