2. 3(2X – 3) – 2(1-X) – (X+3) = 0.
Tolong bntu ya. sma cara nya.
1. -2X + 5 = – (X + 9)
Jawaban Terkonfirmasi
1. -2x + 5 = -(x + 9)
-2x + 5 = -x – 9
<=> -2x + x = -9 – 5
<=> -x = -14
<=> x = 14
2. 3(2x – 3) – 2(1 – x) – (x + 3) = 0
<=> 6x – 9 -2 + 2x – x – 3 = 0
<=> 6x + 2x – x – 9 – 2 – 3 = 0
<=> 7x – 14 = 0
<=> 7x = 14
<=> x = 14/7
<=> x = 2

1. -2X + 5 = – (X + 9)
-2X + 5 = -x -9
5+9 = -x + 2x
14 = x
2. 3(2X – 3) – 2(1-X) – (X+3) = 0.
6x – 9 – 2+ 2x – X – 3= 0
6x + 2x -x = 9 +2 +3
7x = 14
x = 14 : 7 = 2
Maaf kalo ada yg salah
