Can anyone get the answer with an explanation i dont understand it

Answer:
[tex]d=\frac{2w(c-2)}{5} [/tex]
Step-by-step explanation:
The given formula is:
c=5d+4w/2w
We need to find d.
Multiply 2w on both sides, we get
c x 2w= 5d+4w/2w x 2w
2cw=5d+4w
Adding -4w on both sides, we get
2cw-4w=5d+4w-4w.
2cw-4w=5d
2w(c-2)=5d
Dividing by 5, we get
2w(c-2)/5 = 5d/5
2w(c-2)/5 = d
Hence the required formula with subject d is
[tex]d=\frac{2w(c-2)}{5} [/tex]
