Hi there,

Many thanks in advance for the help.

Here is the equation I am struggling to solve:

110 = 1/(1+r) x 32.1/r

How I solve for "r", or perhaps find an LCD with these denominators?

Thanks so much,

Naldo

110 = 1/(1+r) x 32.1/r

$\displaystyle 110 = \frac{32.1}{r(r+1)}$

$\displaystyle r(r+1) = \frac{32.1}{110}$

$\displaystyle r^2 + r - \frac{32.1}{110} = 0$

recommend using the quadratic formula ... - Oct 31st 2012, 10:42 AMNaldoRe: Equation help - LCD with variables
