6x - 7 ( 2x - 3 ) = 3 ( 4x - 3 )

MAPEL = MATEMATIKA
KELAS = 7
BAB = SLPSV

6x -7(2x - 3) = 3(4x - 3)
6x - 14x + 21 = 12x - 9
6x - 14x - 12x = -9 - 21
6x - 26x = -30
-20x = -30
x = -30/-20
x = 3/2

semoga membantu

6x-7(2x-3)=3(4x-3)
6x-14x+21=12x-9
-8x+21=12x-9
-8x-12x=-21-9
-20x=-30
x=-30/-20
x=3/2
x=1 1/2

Semoga bisa membantu...
