Tentukan Nilai x yang memenuhi persamaan berikut
Jawaban:
F. 8 - x = 2 + 2x
-x - 2x = 2 - 8
-3x = -6
x = 2
G. 3x - 3 = 2x + 7
3x - 2x = 7 + 3
x = 10
H. 5x - (x + 5) = x + 7
5x - x - 5 = x + 7
5x - x - x = 7 + 5
3x = 12
x = 4
I. 1/2x + 3 = 1/3
6(1/2x + 3) = 1/3 × 6
3x + 18 = 2
3x = 2 - 18
3x = -16
x = -16/3
J. 4/x = 2/3
2x = 12
x = 6
