Question

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

Answer 1

Step(iii)

The value of 'f' = 3

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
