1. Jawaban BSunShine
2 + 3(1 - 2x) = 5 - 2(2x + 3)
2 + 3 - 6x = 5 - 4x - 6
5 - 6x = -4x - 1
-6x + 4x = -1 - 5
-2x = -6
x = 3
-------------------------------
3(x + 4) = 6(x - 2)
3x + 12 = 6x - 12
3x - 6x = -12 - 12
-3x = -24
x = 8
Semoga membantu ^_^ -
2. Jawaban danisetiawan3
a. 2 + 3(1-2x)= 5 -2 (2x +3)
2 + 3 -6x = 5 - 4x -6
5 -6x = -1 -4x
5+1 = -4x+6x
6 = 2x
x = 6÷2 =3
b. 3(x+4) = 6(x-2)
3x+12 = 6x-12
3x - 12x = -12 - 12
-3x. = -24
x = -24 ÷ -3
x = 8
