Tlg bantu jawab thx:)

1. 2 (3x + 1) = 5 (x – 2)

= 6x + 2 = 5x – 2

= 6x – 5x = -2 – 2

= x = -4

2. 3 (2x – 4) = 4 (3x + 5)

= 6x – 12 = 12x + 20

= -12 – 20  = 12x – 6x

= -32 = 6x

= 6x = -32

= x = -32/6

x= -5,3

3. 5 (x +3) = 3 (4x – 1) +8

= 5x + 15 = 12x – 3 +8

= 5x – 12x = -15 -3 +8

= -7x = -10

= -x = -10/7

= x= 1,3

Semoga membantu dan maaf kalau ada yang salah 🙂

1.
6x+2=5x-10
6x-5x=-10-2
x=-12
2.
6x-12=12x+20
6x-12x=20+12
-6x:-6=32:-6
x=-5,3
3.
5x+15=12x-3+6
5x-12x=3-15
-7x=-12
-7x:-7=-12:-7
x=1,7
