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

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
