Question

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

Answer 1

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

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

$5( - 2x - 1) = 5( - x + 1)$

$- 10x - 5 = - 5x + 10$

$- 10x + 5x = 10 + 5$

$- 5x = 15 \times ( - 1)$

$5x = - 15$

$x = \frac{ - 15}{5}$

$x = - 3$

Resposta: X= -3
