Question

18 = 752 + 20f / 44 + f

Answer 1

Answer:

Step-by-step explanation:

18=752+20f/44+f

18(44+f)=752+20f

792+18f=752+20f

792-752=20f-18f

40=2f

f=40/2

f=20

Answer 2

Step-by-step explanation:

752 + 20f /44 + f = 18

752 + 20f + 44f/44 = 18

752 + 64f/44 = 18

33088 + 64f / 44 = 18

33088 + 64f = 792

33088 - 792 = - 64f

32296 = -64f

32296/-64 = f

f = - 504.265
