Question

nx-r=p, for x solve each equation or formula for the variable specified.

Answer 1

nx-r=p ... Start with the given equation


nx-r+r=p+r ... Add r to both sides.


nx = p+r ... Add and simplify


nx/n = (p+r)/n ... Divide both sides by n


x = (p+r)/n ... Divide and reduce nx/n to get x


So the answer is x = (p+r)/n
