Answer 1

Explicación paso a paso:

a)

$- 4x + 3 = 11 \\ - 4x = 11 - 3 \\ - 4x = 8 \\ x = \frac{ 8}{ - 4} \\ x = - 2$

b)

$2 \times ( - 4) + 2x = - 2 \\ - 8 + 2x = - 2 \\ 2x = - 2 + 8 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3$

c)

$x + 2x - 5 = 4x + 6 \\ x + 2x - 4x = 6 + 5 \\ - 1x = 11 \\ - 1x \times (- 1) = 11 \times ( - 1) \\ x = - 11$

d)

$4 + 2(x - 6) = x - 5 \\ 4 + 2x - 12 = x - 5 \\ 2x - x = - 5 - 4 + 12 \\ 1x = 3 \\ x = 3$

e)

$2(x + 3) - 8x = 2(5 - 2x) \\ 2x + 6 - 8x = 10 - 4x \\ 2x - 8x + 4x = 10 - 6 \\ - 2x = 4 \\ x = \frac{4}{ - 2} \\ x = - 2$
