Question

Persamaan Linear :

1. 4x + 5 = 3x - 7
2. 3a - 1 = a + 9
3. 2 ( 3p - 4 ) = 4p + 6
4. 2/3 ( 5x + 2 ) = 2 ( x + 2 )
5. 2x -1 / 3 + 6x + 4 /2 = 4x + 3
6. ( 6x - 4 ) ( x + 3 ) = @x ( 3x + 4
7.( 2x + 3 ) ( 8x - 5 ) = ( 4x + 1 )

Tolong dikasih rumusnya Thx

Answer 1

Langkah pertama , satukan yang mempunyai variabel . contoh pada no 1
 4x + 5 =3x - 7
 4x - 3x = -7-5
 x = -12 

Answer 2

1. 4x + 5 = 3x - 7
4x - 3x = -7 -5
x = -12
2. 3a - 1 = a + 9
3a -a = 9+1
2a = 10
a=5
3. 2 (3p - 4) = 4p + 6
6p - 8 = 4p + 6
6p - 4p = 6 + 8
2p = 14
p = 7
5. 2x - 1/3 + 6x + 4/2 = 4x + 3
(2x + 6x - 4x) = (1/3-1/2+3/1)
4x = 1/3
x = 1/3 : 4
x = 0.83
