1) 5/2x + 3/2x = 5+3/2x = 8/2x = 4x

2) 3/(x+2) + 2/(x-3) = (3(x-3) + 2(x+2)) / (x+2)(x-3)
= ((3x-9) + (2x+4)) / (x+2)(x-3)
= (3x+2x-9+4)/x kuadrat-x-6
= (5x - 5) / x kuadrat - x - 6
= 5(x - 1) / x kuadrat - x - 6

3) 4/(x+3) - 5/(x-1) = (4(x-1) - 5(x+3)) / (x+3)(x-1)
= ((4x-4) - (5x+3)) / (x+3)(x-1)
= (4x-4-5x+3) / (x+3)(x-1)
= -x-1 / x kuadrat + 2x - 3

4) (2a/3x) x ((2x-6xy)/12a) = (a/3x) x ((2x-6xy)/6a)
= (1/3x) x ((2x-6xy) /3))
= (2x-6xy) / 9x
= (2-6y) / 9

5) 12/ (x-3)(x+3) : 3/(x+3)
= (12 / (x-3)(x+3)) x ((x+3)/3)
= 4/(x-3)
