Answer:

  • Mark’s sister weights 65 pounds

---------------------------------------

Mark's weight is 75 pounds ad his sister's weight is w.

Together, he and his sister weigh 10 pounds more than two times the weight of his sister,

Set up equation:

  • 75 + w = 10 + 2w

Solve it for w:

  • 75 + w = 10 + 2w
  • 2w - w = 75 - 10
  • w = 65
