Answer 1

Explicación paso a paso:

$a) \\ 3x + 2(x + 3) = 2x \\ 3x + 2x + 6 = 2x \\ 5x + 6 = 2x \\ 6 = 2x - 5x \\ 6 = - 3x \\ \frac{6}{3} = x \\ 2 = x$

$b) \\ 6(2x - 3) + 3(x - 4) = - 15 \\ 12x - 18 + 3x - 12 = - 15 \\ 15x - 30 = - 15 \\ 15x = - 15 + 30 \\ x = \frac{15}{15} \\ x = 1$

$c) \\ 8x - (x + 6) = 22 \\ 7x + 6 = 22 \\ 7x = 22 - 6 \\ x = \frac{16}{7}$
