Question

What is the f?
f/5 - (-13) = 12

Answer 1

f= -5

Explanation:

f/5-(-13)=12

remove the parenthesis and replace the negative with a positive.

f/5+13=12

multiply all by 5

f+65=60

move constant to the right

f=60-65

subtract 60 to 65

-----------------

f= -5

-----------------

Answer 2

Explanation:

`(f)/(5) - ( - 13) = 12`

`(f)/(5) + 13 = 12`

`(f)/(5) = 12 - 13`

`(f)/(5) = - 1`

Now cross multiply

Therefore f = -5
