Answer 1

Explicação passo-a-passo:

$1) \: 3x + 4.(1 + x) + 2 = 5x - x - 6 \\ 3x + 4 + 4x + 2 = 4x - 6 \\ 7x + 6 = 4x - 6 \\ 7x - 4x = - 6 - 6 \\ 3x = - 12 \\ x = \frac{ - 12}{3} = x = - 4$

$2) \: a)3 + x = 0 \\ x = - 3 \\ \\ b)23x + 2 = 2 \\ 23x = 2 - 2 \\ 23x = 0 \\ x = \frac{0}{23} = 0 \\ \\ c)12 - 7 + 4x = 25 \\ 5 + 4x = 25 \\ 4x = 25 - 5 \\ 4x = 20 \\ x = \frac{20}{4} \\ x = 4 \\ \\ d)5x - 3x = 30 \\ 2x = 30 \\ x = \frac{30}{2} \\ x = 15$
