tolong dong..........

semoga membantu yahghh,,,,,

2.) 3/(x+2) + 2/(x-3) = 3(x-3)+2(x+2)/(x+2)(x-3) = 3x-9+2x+4/x'2-3x+2x-6 = 5x-5/x'2-x-6

3.) 4/(x+3) - 5/(x-1) = 4(x-1)-5(x+3)/(x+3)(x-1) = 4x-4-5x-15/x'2-x+3x-3 = -x - 19/x'2+2x-3

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

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

6.) => langsung jawabannya aja yahh,, caranya panjang. -x-3y/7x-y
