Verified Answer :

C = wtc/1000
1000C = wtc      [multiply both sides by 1000]
w = 1000C/tc      [divide both sides by tc]

For this case we have the following equation:
 \(C = \frac{wtc}{1000}\)
 To clear w, we must follow the following steps:
 1) The value of t multiplied by c pass to divide the other side of the equation:
 \(\frac{w}{1000} = \frac{C}{tc}\)
 2) the value of 1000 is passed to multiply to the other side of the equation:
 \(w = \frac{1000C}{tc}\)
 Answer:
 
The cleared equation for w is:
 
\(w = \frac{1000C}{tc}\)
