1. Jawaban Sharon
1) 5x = 25 + 2x
5x - 2x = 25
3x = 25
x = 25/3
atau x = 8 1/3
2) 2x - 6 = 8x + 5
2x - 8x = 5 + 6
-6x = 11
x = 11/-6
atau x = -1 5/6
3) 3x - 4 = 2x + 1
3x - 2x = 1 + 4
x = 5
4) 3x - 12 = 7x - 8
3x - 7x = -8 + 12
-4x = 4
x = 4/-4
x = -1
5) 6x - 4 = 3x + 5
6x - 3x = 5 + 4
3x = 9
x = 9/3
x = 3
