Seven times a number plus three times another number equals negative one. The sum of the two numbers is negative three. What are the numbers, provide the answer in the format of (x, y)

(2, -5)

Step-by-step explanation:

Let x = 1st no.

     y = 2nd

(1)      7x + 3y = -1          (2)    x + y = -3

                                                  y = -x - 3    Substitute -x - 3 for y in equation 1

         7x + 3(-x - 3) = -1

         7x - 3x - 9 = -1

                 4x - 9 = -1

                 4x = 8

                   x = 2                       y = - 2 - 3

                                                  y = -5

choice b is correct
