The way you actually wrote it: x+2(57). This is just x+114 and does not help you find x.The way I think you meantto write it: x+2x=57. 3x=57. x=19
The sum of the first 57 natural numbers is 1,625.
The sum of 57 is 57 itself. In mathematical terms, the sum refers to the result of adding two or more numbers together. Therefore, when you add 57 to another number or to itself, the sum will be the total value of those numbers, which in this case is 57.
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
The expression is: 57+b
A single number can have only one sum: in this case, 57.
2*(x + 21) = 3*abs(x - 5) => x = -5.4 or x = 57.

x+21 = 57
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
