-2(2f-4)=-4(-f+2)

Question

I really need help on my algebra

Answer 1

-2(2f - 4) = -4(-f + 2)         distribute

-4f + 8 = 4f - 8                   add 4f to both sides

8 = 8f - 8                           add 8 to both sides

16 = 8f                              divide both sidesby 8

2 = f

 

Check:

-2(2(2) - 4) = -4(-2 + 2)

-2(4 - 4) = -4( -2 +2)

0 = 0
