1.025t+7.65=P
Swap sides so that all variable terms are on the left hand side.
1.025t=P-7.65
Subtract 7.65 from both sides.
\frac{1.025t}{1.025}=\frac{P-7.65}{1.025}
Divide both sides of the equation by 1.025, which is the same as multiplying both sides by the reciprocal of the fraction.
t=\frac{P-7.65}{1.025}
Dividing by 1.025 undoes the multiplication by 1.025.
t=\frac{40P-306}{41}
Divide P-7.65 by 1.025 by multiplying P-7.65 by the reciprocal of 1.025.
