Tolong bantu kak pliss Tentukan Hp dari persamaan berikut 1) (3×+7)= ×-6 2) (2×-5/×+3)=2 3) (×-5/4)=3×-4 4) (×+7/4)=-5

@
1)  3x + 7 = x - 6
3x - x = - 6 - 7
2x =  -13
x = - 13/2

2) (2x -5)/(x+3) = 2
 2x - 5 = 2(x + 3)
2x - 5 = 2x + 6
2x - 2x = 6 + 5
0x = 11
x = 11/0
x = ~

3) (x-5)/ 4 = 3x - 4
x-5 = 4(3x - 4)
x - 5 = 12x - 16
x - 12x = -16 + 5
-11 x = -11
x = -11/-11
x = 1

4) (x+7)/ 4 = - 5
x + 7 = 4(-5)
x + 7 = - 20
x = -20 -7
x = - 27

1] 3x + 7 = x - 6
=> 3x - x = -6 - 7
=> 2x = -13
=> x = -13/2
=> x = -6,5
HP = {-6,5}

2] (2x - 5)/(x + 3) = 2
=> 2x - 5 = 2(x + 3)
=> 2x - 5 = 2x + 6
=> 2x - 2x = 6 + 5
=> 0 = 11
HP = { } (tidak terdefinisi)

3](x - 5)/4 = 3x - 4
=> x - 5 = (3x - 4) × 4
=> x - 5 = 12x - 16
=> x - 12x = -16 + 5
=> -11x = -11
=> x = -11/-11
=> x = 1
HP = {1}

4] (x + 7)/4 = -5
=> x + 7 = -5 × 4
=> x + 7 = -20
=> x = -20 - 7
=> x = -27
HP = {-27}
