2(x+5)+4(x-3) = 3(2x-4)+5(x+1)

Mapel : Matematika
Kelas : VIII SMP
Bab : PLSV

Pembahasan :
2(x + 5) + 4(x - 3) = 3(2x - 4) + 5(x + 1)
2x + 10 + 4x - 12 = 6x - 8 + 5x + 5
6x - 2 = 11x - 3
11x - 6x = -2 + 3
5x = 1
x = 1/5

Hp : {1/5}

2x+10+4x-12 = 6x-12+5x+5
6x-2 = 11x-7
6x-11x = -7+2
-5x = -5
x = 1
