: I was wondering how to solve this problem.

4c=3d+3
c=d-1 4(d-1)=3d+3 = 4d-4=3d+3 subtract 3d to both sides d-4=3 Add 4 to both sides d=7 how do you post ?'s

I got at least this far:
4(d-1)=3d+3
But now, I dont know if I'm soposed to find out what the variables are first or distribute. If I distribute, I dont kno how to distribute this equation. Can you help me?This question is from textbook Algebra 1
