Answer:

Step-by-step explanation:

Formula

a = 9 / (f - 7)

Note

If you are going to try and isolate f, you must take the 7 with it, assuming that getting f to the left hand side will the your first step. It will be mine.

Solution

a = 9 / (f - 7)                     Multiply both sides by (f - 7) leave the brackets around (f - 7)

a(f - 7) = 9(f - 7)/(f - 7)      Combine

a(f  -  7) = 9                       Remove the brackets

fa - 7a  = 9                        Add 63 to both sides

fa - 7a + 7a = 9 + 7a         Combine

fa = 9 + 7a                        Divide by a

fa/a = (9 + 7a)/a                Simplify

f = (9 + 7a)/a

Answer

f = (9 + 7a)/a

Answer:

[tex]f = \frac{9}{a} +7\\[/tex]

(a ≠ 0)

Step-by-step explanation:

     a = [tex]\frac{9}{f-7}[/tex]

     · f - 7    · f - 7       [multiply by f - 7 to get rid of fraction]

   a(f - 7) =  9

  ÷a           ÷a        [divide by a to help with isloting the variable, f]

      f - 7 =    [tex]\frac{9}{a}[/tex]

       + 7         + 7       [add 7 to both sides to isolate f entirely]

      f      =   [tex]\frac{9}{a}[/tex] + 7
