Question

I have a PS (problem solving) and i need to figure out an equation to get my answer, but I'm stuck. it sounds somewhat like this:
9 over S = 12 over (s-2) minus 3 over (s-6)
if anyone can write this out and solve it i would be very happy. Thank you

Answer 1

This is a 7th grade problem!! Please help me!! its due tomorrow :(

Answer 2

\[\frac{9}{s} = \frac{12}{s-2} -\frac{3}{s-6}\]
combine fractions on right side
\[\frac{9}{s} = \frac{12(s-6)-3(s-2)}{(s-2)(s-6)}\]
distribute and add like terms on top
then cross multiply
\[9(s-2)(s-6) = s(9s-66)\]
expand and set =0
s=18

Thank you so much! :)
