Temukan himpunan penyeslesaian dari persamaan beeikut Tolong bantu dong 1) [ 2x-3 ] = [ x + 2 ] 2) [ 6x ] = 18 3) [ 3x + 2 ] - 5x = 18 4) [-8 ] + [ 2 ] - [ -1 ]

1. 2x - 3 = x + 2
2x - x=2 + 3
x = 5

atau

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

2. 6x =18
x=18-6
x=12

atau
6x = -18
x = -18 -6
x = -24
