## anonymous 5 years ago 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

$\frac{9}{s} = \frac{12}{s-2} -\frac{3}{s-6}$ 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
