Answer 1

Explicación paso a paso:

$3(x - 4) + 6 = 5(x + 1) - 13 \\ 3x - 12 + 6 = 5x + 5 - 13 \\ - 12 + 6 - 5 + 13 = 5x - 3x \\ - 6 - 5 + 13 = 2x \\ - 11 + 13 = 2x \\ 2 = 2x \\ \\ \frac{2}{2} = x \\ \\ 1 = x$

2)

$3(x + 1) + 4(2x - 1) = 5(x + 5) - 2(x - 3) \\ 3x + 3 + 8x - 4 = 5x + 31 - 2x + 6 \\11x - 1 = 3x + 31 \\ 11x - 3x = 31 + 1 \\ 8x = 32 \\ \\ x = \frac{32}{8} \\ \\ x = 4$

3)

$5(x + 1) + 3(x - 2) = 3(3x - 2) \\ 5x + 5 + 3x - 6 = 9x - 6 \\ 8x + 5 - 6 = 9x - 6 \\ 5 + 6 - 6 = 9x - 8x \\ 5= x$
