Question 24112
1) Solve for r:
{{{A = P(1+rt)}}} Divide bothe sides of the equation by P.
{{{A/P = 1+rt}}} Now Subtract 1 from both sides.
{{{(A/P)-1 = rt}}} Finally, divide both sides by t.
{{{((A/P)-1)/t = r}}}
Another way to write this is:
{{{r = (A-P)/Pt}}}

2) Solve for T:
{{{PV = nRT}}} Divide both sides of the equation by nR
{{{PV/nR = T}}} or
{{{T = PV/nR}}}
