235-2.5t=W
Swap sides so that all variable terms are on the left hand side.
-2.5t=W-235
Subtract 235 from both sides.
\frac{-2.5t}{-2.5}=\frac{W-235}{-2.5}
Divide both sides of the equation by -2.5, which is the same as multiplying both sides by the reciprocal of the fraction.
t=\frac{W-235}{-2.5}
Dividing by -2.5 undoes the multiplication by -2.5.
t=-\frac{2W}{5}+94
Divide W-235 by -2.5 by multiplying W-235 by the reciprocal of -2.5.
