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
