Maths problem that I shouldn't be having so much difficulty with
16 minutes ago, LOUOS said:U = K- P This is the original expression and the task was to rearrange to make D the subject.
3D-Y
-K
(U-K)= -P
3D-Y
*(3D-Y)
(U-K)(3D-Y)=-P
3DU-3DK-UY+KY=-P
this is as far as I have been able to get so far. If its obvious to you what to do next would you mind explaining rather that commenting the answer with some hilarious quip like "git gud".
You were like 1 or 2 steps off, I always used to forget this. move every factor with D onto the same side on their own so you have
3DU-3DK=....
factorise that side to
D(3U-3K)=...
then divide it all by that factor so you are left with B. this is what I beleive it is
D=-P+UY-KY/3U-3K
