I am having a hard time trying to get the answers to a few problems. I was hoping that someone could help me?
u/11=8/13 solve for u. I came up with the answer of u=6.67923
-15/z-1=18/z
and
2w/3z times 7z/4wz I got the answer 7*z/6 but I do no think that is correct.
and x+1/4x+8*x^2-x-6/x^2-1 the answer I got was (x-3)/4(x-1)
Can someone please help me??
