Is the denominator just the variable? Or does it include the addition of the whole number?
if so then the answer is : D = 24
you multiply each side by the other sides denominator and get:
(3)(D+12)=(4)(D+3), then just work it out

agreed. this is confusing because parentheses are used when they're not needed, calling into question the user's correct usage of them throughout. there are no parentheses in the denominator, so the denominator is the variable only. if the numeral should be included, this correction should be made by the asker.

(3/1+3)=(4/1+12) so 3+1=4x3=12 so d is equal to 1

3/d + 3 = 4/d + 12
d(3/d + 3) = d(4/d + 12)
3 + 3d = 4 + 12d
-1 = 9d
-1/9 = d

That looks good! Again, it all depends on the denominator. Thanks
