the sum of three numbers is 64. the second number is 3 less than the first number, the third number is 11 less than twice the first. what are the three numbers?

Let x represent the first number; 2x - 3 then represents the second number. x + 2x - 3 = 75 3x = 78 x = 26 2x - 3 = 49 So the numbers are 26 and 49.

Number one = x Number two = y Number three = z x + y + z = 26The second number is twice the first. y = 2x The third number is 6 more than the second. z = y + 6 z = 2x + 6 x + 2x + (2x + 6) = 26 5x = 20 x = 4 Number one = 4 Number two = 8 Number three = 14

If the second number is a multiple of the first, then the first numberis the greatest common factor of both numbers.

Let the first number be x, the second number be 3x and the third number be 6x-9: x+3x+6x-9 = 101 10x = 101+9 10x = 110 x = 11 So the numbers are: 1st = 11, 2nd = 33 and the 3rd = 57
