Me ajudem, pfv!

A)
$\\\\ 4x - 2x + 3(x + 1) + 2 - 3$
B)
$(x + 4) \geqslant 10(x - 3)$
​

Answer 1

Explicação passo-a-passo:

$4x - 2x + 3(x + 1) + 2 - 3 \\ 2x + 3x + 3 + 2 - 3 \\ 5x + 2 \\ \\ x + 4 \geqslant 10(x - 3) \\ x + 4 \geqslant 10x - 30 \\ x - 10x \geqslant - 30 - 4 \\ - 9x \geqslant - 34 \\ 9x \leqslant 34 \\ x \leqslant \frac{34}{9}$
