Question

Make u the subject of the formula in 1/u + 1/v =2/f

Answer 1

Answer:

1/(2/f - 1/v) = u

Step-by-step explanation:

1/u + 1/v = 2/f

Step1 : Move 1/v to the left

1/u = 2/f - 1/v

Step2: Multiply both sides by u

1 = u(2/f - 1/v)

Step 3: divide both sides by 2/f - 1/v

1/(2/f - 1/v) = u
