Both are related because u can multiply the answer to find a devision problem and you can divide a answer to find ur multiplication problem and find ur answer hope this helps
B+c/d=a subtract b from both sides
c/d=a-b multiply both sides by d
c=d(a-b) or if you prefer
c=ad-bd
Note: if you meant a=(b+c)/d, multiply both sides by d
b+c=ad subtract b from both sides
c=ad-b
Is there an image attached?
The awnser to this is 10x
