Answer:

It will be 4

Steps:

1+ 3(4f-7)= 28

3(4f-7)=28-1=27

(4f-7)=27÷3=9

4f=9+7=16

f=16÷4=4

Answer:

f = 4

Explanation:

1 + 3(4f - 7) = 28 ( subtract 1 from both sides )

3(4f - 7) = 27 ( divide both sides by 3 )

4f - 7 = 9 ( add 7 to both sides )

4f = 16 ( divide both sides by 4 )

f = 4
