You must use brackets in these kind of problems to properly establish the correct order of operations.
e.g. #4
3/(x+3) - 1/(x-2) = 5/(2(x+3)) , notice I factored the last one
now multiply each term by the LCD, that will "clear" all the denominators
6(x-2) - 2(x+3) = 5(x-2)
6x - 12 - 2x - 6 = 5x - 10
-x = 8
x = -8
try the others the same way
