Question

Change the formula to make ‘u’ the subject. (3 marks)

P = W+2u

t

Answer 1

Answer:

if P = W+2u

then finding U formula should be

U = P/2 - W/2

or

U = (P-W)/2

Answer 2

Answer:

u = (P - W)/2

Step-by-step explanation:

Given that, P = W + 2u

Interchanging the sides, W + 2u = P

=> W + 2u - W = P - W  [subtracting W from both sides]

=> 2u = P - W

=> 2u/2 = (P - W)/2  [dividing both sides by 2]

∴ u = (P - W)/2
