Multiply the entire bottom eqn by 3 to get -3x + 9y = -15.
Add the two eqns together to cancel the x's and you get 11y = -11
Solve for y to get y = -1
Pick one of the two original eqns and plug y back in:
-x + 3(-1) = -5; simplify:
-x -3 = -5
-x = -2
x = 2

So your answer is (2, -1).

Part B
9.58 kg+1.25 kg+0.025 kg = 10.855 kg
So the bag, water bottle, and sleeping bag weigh 0.145 kg less than 11 kg
