Question

Solve F=D+Drt for t.....

Answer 1

`t = (-D+F)/(Dr)`

Explanation:

Step 1: Flip the equation.

• 
  `Drt + D = F`

Step 2: Subtract D from both sides.

• 
  `Drt + D - D = F - D`
• 
  `Drt = -D + F`

Step 3: Divide both sides by Dr.

• 
  `(Drt)/(Dr) = (-D+F)/(Dr)`
• 
  `t = (-D+F)/(Dr)`
