Let's call this unknown number, x.
So then we can put together the equation using the information from the question:
[tex] 10*(\frac{1}{2}*x+6)=8 [/tex]
Then we start by distributing this 10 to both the [tex] \frac{1}{2}x [/tex] and the 6:
[tex] 5x+60=8 [/tex]
Then we subtract 60 on both sides:
[tex] 5x=-52 [/tex]
Then we divide both sides by 5 to solve for x:
[tex] x=\frac{-52}{5} [/tex] or [tex] -10\frac{2}{5} [/tex]
