pls solve this

1) 7y/(y-2)(y+2) + 5/y-2 = 2y/(y-2)(y+2)

2) 4x/(x+4)(x-4) + 5/x+4 = 5x/(x+4)(x-4)

3) 4/x+4 = -5/(x-4)(x+4) + 1


thank you!!!

You are in a windowless room with one door and 4 light switches in the off position. One of the switches controls a light bulb in another room which you cannot see. The other three switches do nothing. You may manipulate the switches however you wish, but once you leave the switch room to go to the light bulb room you cannot go back. How can you determine which switch controls the light bulb?

Two trains are moving toward each other on the same track, each traveling at 25 mph. When they are 100 miles apart a fly starts at the front of the first train and flies toward the second at 37 mph. When it reaches the second train it instantly reverses direction and flies back toward the first, again at 37 mph. It continues in this manner, flying back and forth between the trains at 37 mph until the trains collide and the fly is squished. How far does the fly fly?

I really want to do better at the math section of the GMAT, but all the test prep companies offer is quick fixes that are supposed to help you guess better as well as tricks. I know all the basic concepts, so I can review how to find an area of a circle all day and it doesn't help me.

I want to learn how to actually get better at understanding and solving complex math problems so that I can do better on the test. Is this possible?
