Answer 1

48/3

Answer 2

16

Answer 3

I just checked it and thats not the answer. It is quite confusing. Thank you though (:

Answer 4

P + J = 64 (given in problem)
J = 64- P (solving for J)
P = 3J (given in problem)
P = 3(64-P) (substituting step one solution into equation)
P = 192-3P (distributive law of multiplication)
4P = 192 (adding 3P to both sides)
P = 48 (divide both sides by 4)
J = 64 - 48 (substituting our solution of P in with step 2, to solve for J
J = 16 (simplifying the expression)

CHECK
Does J = three times P
16 x 3 = 48. Yes.
Does J + P = 64?
16+48 = 64. Yes!
