Monica has a jewelry box of earrings. This box contains 4 pairs of plain gold earrings, 11 pairs of gold earrings with diamonds, 2 pairs of plain silver earrings, and 5 pairs of silver earrings with diamonds. If she picks a pair of earrings at random from the box, what is the probability that she picks a pair with diamonds? A. 8/11

B. 7/11

C. 1/2

D. 5/22

This does not make sense

The operation is suck a c@ck? !

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
