Solve the equation for the specific variable.

Question

Can someone please help me understand and solve this:

A=P+PRT; Solve for R

Answer 1

A=P+PRT; Solve for R

All you do is move the letters around just like if they were numbers.

A = P + PRT !st move what is not attached to the R by subtracting the P that is by itself

A - P = PRT 2nd now move over what is attached to the R but keep the R where it is at by dividing P and T to on both side

A - P = R

PT

I hope this helped you out.

Answer 2

A = P + PRT

A - P = PRT

(A - P) / PT = R
