-70000t-147000=V
Swap sides so that all variable terms are on the left hand side.
-70000t=V+147000
Add 147000 to both sides.
\frac{-70000t}{-70000}=\frac{V+147000}{-70000}
Divide both sides by -70000.
t=\frac{V+147000}{-70000}
Dividing by -70000 undoes the multiplication by -70000.
t=-\frac{V}{70000}-\frac{21}{10}
Divide V+147000 by -70000.
