You can use elimination by adding the two equations to "cancel out" one of the variables. in this example y will cancel out.

2x + y = 3
+
2x - y = 4
________
2x = 6
x = 3

now that we know our x value, we can plug it into one of the other equations to get our y value.

2(3) + y = 3
6 + y = 3
y = -3

your answer for this system is x=3, y=-3

If nCk represents the number of ways k parts can be chosen from a pool of n, the probability of interest is the complement of the probability of selecting all good parts.
1 - (167C3)/(170C3) = 42,085/804,440 ≈ 0.0523

_____
nCk = n!/(k!(n-k)!)
