Question

Slove the equation f-(-4)=12.
f =-8.
f =16.
f =8.
f = -9​

Answer 1

Explanation:

f-(-4)=12(Remove brackets)

f--4=12(Negative and negative is going to give you positive)

f+4=12(Group Like Terms)

f=12-4(Subtract)

f=8

Then that will be the final answer

Answer 2

`\huge\boxed{f=8}`

Explanation:

`f-(-4)=12\to f+4=12\qquad|(-)(-)\to(+)\\\\f+4=12\qquad|\text{subtract 4 from both sides}\\\\f+4-4=12-4\\\\f=8`
