Answer:
[tex]f=-8[/tex]
Step-by-step explanation:
[tex]8+4f=3f[/tex]
[tex]8+4f-4f=3f-4f[/tex] (Subtract [tex]4f[/tex] from both sides of the equation to isolate [tex]f[/tex])
[tex]8=-f[/tex] (Simplify)
[tex]-f=8[/tex] (Symmetric Property of Equality)
[tex]\frac{-f}{-1} =\frac{8}{-1}[/tex] (Divide both sides of the equation by [tex]-1[/tex] to get rid of [tex]f[/tex]'s coefficient; remember that [tex]-f=-1*f[/tex], so [tex]-f[/tex] has a coefficient of [tex]-1[/tex])
[tex]f=-8[/tex] (Simplify)
Hope this helps!
