Im in 9th grade freshman year, blehh.

And I need help on this one problem.

16= d-12/14

or sixteen equals d minus 12 over 14

if that helps.

Anyone care to help?

Add $\frac{12}{14}$ (or, more simply, $\frac{6}{7}$ ) to both sides of that equation, and then see what it looks like.

well d-12 is over 14

I don't like ArcSines answer, but it's perfectly acceptable. You got the wrong answer, though.

Multiply both side of the equation by 14. then it will make more sense, hopefully.

I don't like ArcSine's answer either, given that the equation seems to be

$16\ =\ \frac{d-12}{14}$ , upon further clarification by Soc.

(And Galactus just mentioned the other day the importance of using grouping symbols to remove any ambiguities... I shouldn't've tried to 'interpret'. My bad, boys... )

OK, Soc, scratch my previous one and do just as KISS instructed. And use parentheses next time.

That's OK, ArcSine. I interpreted exactly like you did. (Although I still would have multiplied by 14 first.)
