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 the equation by 14., then it wil 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.)
