Answer:

  • -1 and 2

Step-by-step explanation:

Let the numbers be x and y

Three times the first number minus two times the second number equals -7:

  • 3x - 2y = -7

The second number equals one less than negative three times the first number:

  • y = -3x - 1

Substitute y in the first equation and solve for x:

  • 3x - 2(-3x - 1) = -7
  • 3x + 6x + 2 = -7
  • 9x = -9
  • x = -1

Find the value of y:

  • y = -3(-1) - 1
  • y = 3 - 1
  • y = 2

The numbers are -1 and 2
