d- =d+4
This makes no sense as is.
d-1 = d+4 can't be solved. Think about taking 'd' from both sides you are left with -1=4.
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
