2x + 7 = 33
2x = 33 - 7
2x = 26
X = 26/2
X = 13

The difference between a number x and twice y is equal to fifteen.
To write twice the sum of a number and 600, you first express the number as a variable, such as ( x ). The sum of the number and 600 can be written as ( x + 600 ). Therefore, twice this sum is represented as ( 2(x + 600) ).
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!

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