The sum of two numbers is six what number is 15 less than two times the second number what are the numbers

9 and -3

Step-by-step explanation:

   Let the first number be x

   Second number = y

                     x + y = 6

                           x = 15 - 2y

        15 - 2y + y = 6

                15 - y = 6

                      -y = 6 - 15

                       -y = -9 ( - sign gets cut cuz there is - sign at both the sides)

      Therefore, first number = 9

             x + y = 6

             x = 9 = 6

             x = -3

   Therefore, second number = -3

  Proof:

9 + (-3) = 6

Hope this helps

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
