Answer:

x = 1 - 14y

Step-by-step explanation:

  1. I will solve for x.
  2. We have 3x + 7y = -3 - x - 7y = 1
  3. Add the -x on both sides.
  4. 4x + 7y = -3 - 7y = 1
  5. Add the 7y on both sides.
  6. 4x + 14y = -3 = 1
  7. Add the -3 to the 1.
  8. 4x + 14y = 4
  9. Divide by 4 (from the 4x) on both sides.
  10. x + 14y = 1
  11. Subtract the 14y.
  12. x = 1 - 14y

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
