4x+8/8x-9=4/3 mohon dibantu dijawab

Bab Persamaan Linear
Matematika SMP Kelas VII

(4x + 8) / (8x - 9) = 4/3
3 (4x + 8) = 4 (8x - 9)
12x + 24 = 32x - 36
12x - 32x = -36 - 24
-20x = -60
x = -60/-20
x = 3

(4x + 8)/(8x - 9) = 4/3
=> (4x + 8) × 3 = 4 × (8x - 9)
=> 12x + 24 = 32x - 36
=> 32x - 12x = 24 + 36
=> 20x = 60
=> x = 60/20
=> x = 3
