selesaikan persamaan berikut! 1.3(x-4)=7(2x+3) 2.-8(2x-1)=4(3+4x) 3.3-4(x-5)=12+3(2x-4) 4.6x=-3(x-4+9) 5.7x=2(x-8)+3(x+2) sama caranya ya,pliss

1.
3(x-4) = 7(2x+3)
3x-12 = 14x + 21
3x-14x = 21 + 12
-11x = 33u
x = 33/-11
x=-3

2.
-8(2x-1) = 4(3+4x)
-16x+8 = 12 + 16x
-16x - 16x = 12-8
-32x = 4
x = 4/-32
x = - 1/8

3.
3-4(x-5) = 12+3 (2x-4)

4.
6x = -3(x-4+9)
6x = -3x +12-27
6x+3x =

5.
7x = 2(x-8) + 3(x+2)
7x = 2x -16 + 3x + 6
7x = 2x+3x -16 +6
7x = 5x + 10
7x - 5x = 10
2x = 10
x = 10/2
x = 5

Soal 1.
3(x - 4) = 7(2x + 3)
3x - 12 = 14x + 21
3x - 14x = 21 + 12
- 11x = 33
x = 33 ÷ (-11)
x = - 3

Soal 2.
-8(2x -1) = 4(3 + 4x)
-16x + 8 = 12 + 16x
- 16x - 16x = 12 - 8
-32x = 4
x = 4 ÷ (-32)
x = -¹/₈

Soal 3.
3 - 4(x - 5) = 12 + 3(2x - 4)
3 - 4x + 20 = 12 + 6x - 12
23 - 4x = 6x
6x + 4x = 23
10x = 23
x = 23 ÷ 10
x = 2,3

Soal 4
6x = -3(x - 4 + 9)
6x = -3(x + 5)
6x = -3x - 15
6x + 3x = - 15
9x = -15
x = -15 ÷ 9
x = - (⁵/₃) = -1 ²/₃

Soal 5. 
7x = 2(x - 8) + 3(x + 2)
7x = 2x - 16 + 3x + 6
7x - 2x - 3x = 6 - 16
2x = -10
x = -10 ÷ 2
x = -5
