Hello,

Just doing some review equations for my Intermediate Algebra class and I'm stumped on one.

d- =d+4

That is how the equation is written. I would assume that there's a 1 after the minus sign making it:

d-1=d+4

then I multiplied both sides by (1/d+4) giving me: (d-1)/(d+4)

Now I'm not sure what to do. Any help on how to solve this equation would be greatly appreciated. Thanks
