----- - ------- =1
2 3

Answer 1

1. a.2(x+3)-X=3(2-X)+4
.......2x + 6 - x = 6-3x+4
.......2x - x +3x = 6 +4 -6
.......4x = 4
........x=4/4
.......x=1

b.x-2        X-4
  -----    -  -------    =1
   2            3
disamain pnybtnya jd 6

3x-6/6 - 2x-8/6 = 1
3x - 2x-8-6/6 = 1
3x-2x-8=1
3x-2x=1+8
x=9
