1. dicoret x atas dengan x bawah , jadi 3b-b/c-3c

trus 3b-1b/ 1c-3c

jadi 2b/-2c= -b/c

b = 1b sama c=1c karena gaada angka artinya 1

2. soalnya sama kek no 1

3. 3/x+1+3/x-1

3(x-1)/(x-1)(x+1) + 3(x+1)/(x-1)(x+1)

3(x-1)+3(x+1)/(x-1)(x+1)

6x/(x-1)(x+1)

6x/x²-1

4. x/x+y + y/x-y

x(x-y)/(x-y)(x+y)+y(x+y)/(x-y)(x+y)

x(x-y)+y(x+y)/(x+y)(x-y)

5. 4a/3x - 4/2x

8a/6x-12/6x

(8 x a) - 12/6x

-96 a /6x

-16a/x

6. 2/x+3-3/x-2

2(x-2)/(x-2)(x+3) - 3(x+3)/(x-2)(x+3)

2(x-2)-3(x+3)/(x-2)(x+3)

-1x/(x-2)(x+3)

-x/x²-6
