The number is 7.
I think its 6.5 because if 3 is the number doubled then it would be 1.5 and add 5 to that makes 6.5
2n + (-5)
5 and 2
The number is 17.
The number is 45. The sum of its digits i.e. 4+5=9 Five times the sum of its digits i.e. 5 times 9 which is 45
The sum of a number times 3 and 27 is greater than or equal to 15.
five times the sum of a number and 8 is -15.
5x + 6
2x + 5 = 152x = 10x = 5The number is 5.
6+n = 2n+5
Let 'n' represent any number, and 'S' represent sum. S = 5 + 2n
