The difference between a number x and twice y is equal to fifteen.
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
"the sum of 2" and "twice" "a number" "is" "36"2+2x=36 â–
The sum, of the number of sides, is seven!

2x + 7 = 30 - 7 - 7 2x = 23 x = 23/2 x = 11.5
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
The number is 17.
