Question

ME AJUDA POR FAVOR!!! ALGUÉM ME AJUDA EU PRECISO DISSO PRA HOJE!!!!

Answer 1

$\geqslant resolucao \\ \\ \\ \frac{4x + 2}{3} = \frac{18}{5} \\ 20x + 10 = 54 \\ 20x = 54 - 10 \\ 20x = 44 \\ x = \frac{44}{20} \\ x = \frac{11}{5} \\ \\ = = = = = = = = = = = = = = = = = = = = = = \\ \\ \\ \frac{2}{5} = \frac{8}{3x - 4} \\ 6x - 8 = 40 \\ 6x = 40 + 8 \\ 6x = 48 \\ x = \frac{48}{6} \\ x = 8 \\ \\ = = = = = = = = = = = = = = = = = = = = = = = \\ \\ \frac{x - 8}{x} = \frac{2}{3} \\ 3x - 24 = 2x \\ 3x - 2x = 24 \\ x = 24 \\ \\ \\ = = = = = = = = = = = = = = = = = = = = = = \\ \\ \\ \frac{3x}{x - 5} = \frac{4}{1} \\ 4x - 20 = 3x \\ 4x - 3x = 20 \\ x = 20 \\ \\ = = = = = = = = = = = = = = = = = = = = = = \\ \\ \frac{x + 6}{2x} = \frac{1}{4} \\ 4x + 24 = 2x \\ 4x - 2x = - 24 \\ 2x = - 24 \\ x = - \frac{24}{2} \\ x = - 12 \\ \\ = = = = = = = = = = = = = = = = = = = = = \\ \\ \frac{x + 11}{8} = \frac{x + 2}{4} \\ 8x + 16 = 4x + 44 \\ 8x - 4x = 44 - 16 \\ 4x = 28 \\ x = \frac{28}{4 } \\ x = 7 \\ \\ = = = = = = = = = = = = = = = = = = = = = = \\ \\ \frac{5}{7} = \frac{x}{x + 6} \\ 7x = 5x + 30 \\ 7x - 5x = 30 \\ 2x = 30 \\ x = \frac{30}{2} \\ x = 15 \\ \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant$
