Question

3(x + 5) - 2(1 – 3x) = 4 (1 + x) - 2

as duas são questões diferentes! Se puder responder só uma, tá valendo

5(1 - x) + 3(x + 2) < x - 4​

Answer 1

1)

3(x + 5) - 2(1 – 3x) = 4 (1 + x) - 2 <=>

<=> 3x + 15 - 2 + 6x = 4 + 4x - 2 <=>

<=> 3x + 6x + 15 - 2 = 4x + 4 - 2 <=>

<=> 9x + 13 = 4x + 2 <=>

<=> 9x - 4x = 2 - 13 <=>

<=> 5x = - 11<=>

<=> $x=-\frac{11}{5}$

2)

5(1 - x) + 3(x + 2) < x - 4​ <=>

<=> 5 - 5x + 3x + 6 < x - 4 <=>

<=> 3x - 5x + 5 + 6 < x - 4 <=>

<=> -2x + 11 < x - 4 <=>

<=> -2x - x < -4 - 11 <=>

<=> -3x < -15 <=>

<=> x > +5
