1. 6/a + 2 = 4 2. × -12 = 2× + 36 3.2 + ×/4 = 5 Tentukanlah himpunan penyelesaian

1. 6/a + 2 = 4
 pindah ruas, 6/a = 4-2
 6/a = 2
6=2a
a=3

2. × -12 = 2× + 36
    -12-36 = 2x - x
     -48= x

3.2 + ×/4 = 5
   x/4 = 3
  x = 12

1. 6/a = 4-2
   6/a = 2
     6 = 2a
     a = 3

2. x-2x = 36 + 12
       -x = 48
         x = -48

3. x/4 = 5-2
   x/4 = 3
     x = 12
