Answer:


f = -(15)/(4)

Explanation:


f + (1)/(4) = -(7)/(2)

-1/4 -1/4 Subtract 1/4 from each side of the equation to isolate f.


f = -(7)/(2) -(1)/(4) in order to subtract these fractions, we need

to make both fractions have the same denominator.

2 x 2 = 4, so we can just multiply the top and bottom

by 2 to get -14/4. Now we can subtract the fractions.


f = -(14)/(4) -(1)/(4) Since the denominators are the same now, ignore

the bottom and focus on subtracting the numerators.

-14 - 1 = -15.


f = -(15)/(4) This is the final answer.

Answer:

f = -15/4

Explanation:

f+1/4= -7/2

Subtract 1/4 from each side

f+1/4-1/4= -7/2-1/4

f = -7/2 -1/4

Get a common denominator of 4

f = -7/2*/2/2 - 1/4

f = -14/4-1/4

f = -15/4
