It's Math and I really need to pass this class

Question

So basically math isn't my strongest subject it takes me forever to learn in in this problem I need to show my steps 9d+n=5r im solving for d.

Answer 1

9d + n = 5r

You want to get to an equation with d by itself on one side.

Subtract n from both sides and get

9d = 5r - n

Divide both sides by 9 and get

d = (5r - n) / 9
