Question

2+3[x-(3x+1)]=5[x-(2x-1)]​

Answer 1

Resposta:

-6 = x

Explicação:

2+3×[x-(3x+1)]=5×[x-(2x-1)]

2+3×[x-3x-1]=5×[x-2x+1]

2+3×[-2x-1]=5×[-x+1]

2-6x-3=-5x+5

2-3-5 = -5x+6x

-1-5 = -5x+6x

-6 = x

Answer 2

2+3[x-(3x+1)]=5[x-(2x-1)]​
2+3.[x - 3x - 1] = 5.[x - 2x + 1]
2 + 3.[- 2x - 1] = 5.[- x + 1]
2 - 6x - 3 = - 5x + 5
- 1 - 6x = - 5x + 5
- 1 - 5 = 6x - 5x
- 6 = x
x = - 6
