Solution for 100=r*pi-r equation:


Simplifying
100 = r * pi + -1r

Multiply r * ip
100 = ipr + -1r

Solving
100 = ipr + -1r

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '-1ipr' to each side of the equation.
100 + -1ipr = ipr + -1ipr + -1r

Combine like terms: ipr + -1ipr = 0
100 + -1ipr = 0 + -1r
100 + -1ipr = -1r

Add '-100' to each side of the equation.
100 + -100 + -1ipr = -100 + -1r

Combine like terms: 100 + -100 = 0
0 + -1ipr = -100 + -1r
-1ipr = -100 + -1r

Divide each side by '-1pr'.
i = 100p-1r-1 + p-1

Simplifying
i = 100p-1r-1 + p-1

Reorder the terms:
i = p-1 + 100p-1r-1
