Question

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

Answer 1

Answer:

$f = -\frac{15}{4}$

Step-by-step explanation:

$f + \frac{1}{4} = -\frac{7}{2}$

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

$f = -\frac{7}{2} -\frac{1}{4}$          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.

$f = -\frac{14}{4} -\frac{1}{4}$           Since the denominators are the same now,  ignore  

                              the bottom and focus on subtracting the numerators.

                              -14 - 1 = -15.

$f = -\frac{15}{4}$                  This is the final answer.

Answer 2

Answer:

f = -15/4

Step-by-step 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
