What step is wrong -12=4(f-6) step 1 12=4f step 2 4=f step 3
kirza4 [7]

Answer:

Step(iii)

The value of 'f' = 3

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given  - 12 = 4(f-6)

 Multiply  

          - 12 = 4 f - 24

<u><em>Step(ii):-</em></u>

- 12 = 4 f - 24

Adding '12' on both sides, we get

- 12 + 12 = 4 f - 24 + 12

     0 = 4 f - 12

     4f - 12 =0

    4 f = 12

<u><em>Step(iii):</em></u>-

Dividing   '4' on both sides, we get

    f = 3
