Im working on a computer program called Cognitive Tutor.. we use it in class alot. I ran into this problem
Solve for K
hq-mk=ks+nt
I can solve it to this point
k=(-hq+nt)/(-m-s)
The program says to factor out -1 from the denominator ... but when I do it shows up the same and says I still need to do it.... Im confused and wondering if I missed something or if its the program! ???
