Tentukan Himpunan Penyelesaian Dari PLSV Berikut! 1. 5x +4 = 6 +3x 2. 2 (a + 2) = 6 (a - 2) 3. 6 (5 - x) = 8 - 4 (x +3)

1. 5x + 4 = 6 + 3x
5x - 3x = 6 - 4
2x = 2
x = 1
2. 2a + 4 = 6a + 12
2a - 6a = 12 - 4
-4a = 8
a = 8/-4 = 2
3. 30 - 6x = 8 - 4x - 12
30 - 6x = -4 - 4x
-6x + 4x = -4 - 30
-2x = -34
x = -34 / -2 = 17
