NEED HELP

-9 (-16 - f) = 4(1 - 3f)
I keep getting -140/3 as an answer, but apparently that's wrong, I have no idea what I'm not doing right

First use distributive property on both sides of the equation.
-9(-16 - f) = 4(1 - 3f)
144 + 9f = 4 - 12f
Then isolate f on one side of the equation:
3f = -140
f = 46.67 --> (which is equal to -140/3)
I'm sorry I couldn't help more. I don't know why it's wrong. Maybe try putting in it decial form instead.
