Soal 5

X / 2 + ( x -4 ) /3

3 x / 6 + ( 2 x – 8 ) / 6 = 5x – 8 / 6

SOAL 6

( x + 1) / 3 – ( x – 2 ) /4

[ 4 x + 4 /12 ] – [(3x – 6 ) / 12 ]

4 x + 4 – 3x + 6 / 12 = x + 10 / 12

SOAL 7

[ ( 3x – 2 )/ 6 ] – [ ( x+ 4 ) / 3 ]

[ ( 3x – 2 )/ 6 ] – [ 2 ( x + 4 ) / 6 ]

3 x - 2 – 2x – 8 / 6 = x -10 / 6

SOAL 9

4 / a + 4 ( a -2 )

[ 4 ( a -2 ) / a ( a- 2 ) ] + [ 4 ( a) / a ( a – 2 ) ]

[ 4a – 8 + 4a ] / a² - 2a = 8a +8 / a² - 2a

SOAL 11

[ 4 / ( x + 3) ] – [ 3 / ( x – 2) ]

[ 4 . ( x – 2) / ( x + 3) . ( x – 2) – [ 3 . ( x + 3) / ( x – 2) . ( x + 3) ]

4x -8 – 3x – 9 / x² + x – 6

X -17 / x² + x – 6
