Question 926115
Jason weighs 36 pounds. Together he and his sister weigh four pounds more than three times the weight of his sister. What is the weight, w , of Jason's sister?
========================
Equations:
j = 36 lbs
j + s = 3s+4
-----
Substitute for "j" and solve for "s"::
36 + s = 3s+4
2s = 32
sister's weight = 16 lbs.
