Solve the formula for the specified variable.
A = P + PRT for R
To solve the formula for R, we need to isolate R on one side of the equation.
A = P + PRT
First, subtract P from both sides of the equation:
A - P = PRT
Next, divide both sides of the equation by PT:
(A - P)/(PT) = R
Therefore, the formula for R is:
R = (A - P)/(PT)
To solve for R in the formula A = P + PRT, we can follow these steps:
Step 1: Start with the formula A = P + PRT.
Step 2: Subtract P from both sides of the equation to isolate the term PRT. This gives us A - P = PRT.
Step 3: Divide both sides of the equation by PT to solve for R. This gives us (A - P) / PT = R.
Therefore, the formula for R in terms of A, P, and T is R = (A - P) / PT.
