For this case we have the following equation:
 
 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: 
 2)
 2) the value of 1000 is passed to multiply to the other side of the equation: 
 Answer:
 Answer:
 The cleared equation for w is:
