Question

-{3x + 8-[-15 + 6 - (-3x + 2) - (5x + 4)] - 29} = -5​

Answer 1

Explicación paso a paso:

$-{3x + 8-[-15 + 6 - (-3x + 2) - (5x + 4)] - 29} = -5 \\ - 3x + 8-[ - 15 + 6 + 3x - 2 - 5x - 4 ] - 29 = - 5 \\ - (3x + 8 + 15 - 6 - 3x + 2 + 5x + 4 - 29) = - 5 \\ - 3x - 8 - 15 + 6 + 3x - 2 - 5x - 4 + 29 = - 5 \\ - 3x + 3x - 5x = - 5 + 8 + 15 - 6 + 2 + 4 - 29 \\ - 5x = - 11\\ x = \frac{11}{5} \\ x = 2.2$
