    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.
