Im trying to combine this two equations to solve it:
and
I got this far:
0.5 = ( 0.876 - VAf ) / (VAf + 8.76)
Is it possible to find out what VAf is from this?

Images don't work but going on from what you have:
$\displaystyle 0.5 = \frac{0.876 - VAf}{VAf + 8.76}$
$\displaystyle 0.5(VAf + 8.76) = 0.876 - VAf \quad \mbox{Multiplied both sides by } (VAf + 8.76)$
$\displaystyle 0.5VAf + 8.76 = 0.876 - VAf$
Collect like terms as you would normally
