Finance A=P(1 + rt) Solve for r

Chemistry PV=nRT Solve for T

Mechanics v=-gt + v0 Solve for t

Cannot find any formulas that are close to these. Please Help
 
Knowing some basic rules of arithmetic, you can solve any of these simple algebraic equations, for any term that is a variable.

See here: http://www.purplemath.com/modules/solvelit.htm

I'll do the first one for you.

A = P(1 + rt)
Distribute the P into each term in the binomial

A = P + Prt

Subtract P from both sides

A - P = Prt

Divide both sides by Pt

(A - P) / (Pt) = r
