Answer 1

Explicación paso a paso:

$2x + 5 = 8x + 11 \\ 2x - 8x = 11 - 5 \\ - 6x = 6 \\ x = \frac{6}{ - 6} \\ x = - 1$

$3x - 9 = 8x - 17 \\ 3x - 8x = - 17 + 9 \\ - 5x = - 8 \\ x = \frac{ - 8}{ - 5} \\ x = \frac{8}{5}$

$6x + 32 = 36 + x \\ 6x - x = 36 - 32 \\ 5x = 4 \\ x = \frac{4}{5}$

$7x + 18 = 12x - 25 \\ 7x - 12x = - 25 - 18 \\ - 5x = - 43 \\ x = \frac{ - 43}{ - 5} \\ x = \frac{43}{5}$

$4x + 16 = 8x - 14 \\ 4x - 8x = - 14 - 16 \\ - 4x = - 30 \\ x = \frac{ - 30}{ - 4} \\ x = \frac{30}{4}$

$5x + 16 = 17x + 20 \\ 5x - 17x = 20 - 16 \\ - 12x = 4 \\ x = \frac{4}{ - 12} \\ x = - \frac{4}{12} = - \frac{1}{3}$
