Let n= "a number"

"7 is added to twice a number " means 7+2n..
"sum is multiplied by 2" means 2(7+2n)
"the result the same as if the number is multiplied by -8" means 2(7+2n) = -8n
"and 2 is added to product" means 2(7+2n) = -8n+2

So the equation is 2(7+2n) = -8n+2. Find the n and that will be the number.
