The number is 15 times 15 = 225
15
15 - 2x
Let the number be x and so if 2x -7 = 15 then the value of x is 11
32
2*(15 + N)
The number is 15 times 15 = 225
15
n = number 2(n + 15) ======
2x+15
The least possible number for the LCM of 15 and 105 is the same as the least possible number for all the common factors of 15 and 105 and is the LCM of 15 and 105 which just happens to be 105.
2n + 15 = 37
2x-15 = 53
15
because the closest number between these 2 numbers is 15
X = number. 4X + 9 = 2X - 15 ===========
15 - 2x
