Let the numbers be x and y If: x+2y = 3 and 2x+y = 27 Then the simultaneous equations work out as: x = 17 and y = -7
13 and 26
The third number is 112, the numbers are 86, 86, 112, 172
= The sum of two numbers is -42 the first number minus the second number is 52 Find the numbers? =
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

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.
= The sum of two numbers is -42 the first number minus the second number is 52 Find the numbers? =
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
joan decided to use her calculator to find the sum of the first 15 counting numbers instead of the formula. By mistake she entered 16 numbers. She entered one number twice . Her answer was 4 more than a perfect square number. Which number did joan enter twice?
If you say the second number is x, then the first number would be 8x.Therefore x+8x=189x=18x=2(second number)8x=16( first number)
The GCF is the first number.
