I'm only studying for the final (during thanksgiving break no less :) )
I'm in PreCalc, and I've been struggling this entire semester. -.- So any help with studying would be really helpful
I find that I don't quite no where to proceed from here on this one.
The directions on this online study quiz are:
Solve the equation for the indicated variable:
$S = n(n+1)/6$ For "n"
I got as far as: $6*S/n+1 = n$, after performing the following steps:
Multiply on both sides by six.
Divide by $n + 1$
We get: $6*S/n+1 = n$
I know that I need to get that n in the denominator to the other side so I can presumably solve a quadratic but how??? I'm not asking for the answer, just what must I do to get past this step??
