Fynjy0 [20]

Answer:

  • -1 and 2

Step-by-step explanation:

Let the numbers be x and y

<u>Three times the first number minus two times the second number equals -7:</u>

  • 3x - 2y = -7

<u>The second number equals one less than negative three times the first number:</u>

  • y = -3x - 1

<u>Substitute y in the first equation and solve for x:</u>

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

<u>Find the value of y:</u>

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

The numbers are -1 and 2
