Can someone please check my answer? Rearrange (cp-yd)/(pd)=p+y to make d the subject OK, I did cp-yd=pd(p+y) cp=pd(p+y)+yd cp=p^d+pdy+yd factoring out the d cp=d(p^2+py+y) cp/(p^2+py+y)=d

Rearrange (r+s)/8s=(r-s)/8n to make r the subject. OK, I have started by rearranging the formula: 8n(r+s)=8s(r-s) 8nr+8ns=8sr-8s^2 What do I do next?

great, that makes sense, thanks
