Rearrange the formula so that the pronumeral written in square brackets is the subject.

c = 7 + 2d [d]

/

5 - 3d

Do you need to multiply 5 - 3d to the left side so that, c(5 - 3d) = 7 + 2d?

If so I ended up with 5c - 3cd = 7 + 2d

-5c -5c

-3cd = 7 + 2d - 5c

I am not sure what to do from here. Could you please help me?

Thanks a lot.
