What step is wrong -12=4(f-6) step 1 12=4f step 2 4=f step 3

Step(iii)

The value of 'f' = 3

Step-by-step explanation:

Step(i):-

Given  - 12 = 4(f-6)

 Multiply  

          - 12 = 4 f - 24

Step(ii):-

- 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

Step(iii):-

Dividing   '4' on both sides, we get

    f = 3

answer4 to the second power is 16

and 4 to the third power is 64,
