PRA HOJE GENTE POR FAVORR!!!

Answer 1

Resposta:

A)

$\frac{x + 5 + 4}{x = 0} = \frac{9}{0} = 0$

B)

$\frac{10x}{3 + 3} \div \frac{x = 7}{1} = \frac{10.7}{6} \times \frac{1}{x = 7} = \frac{70}{6x = 42} = \frac{70}{7} = 10$

C)

$\frac{3}{x - 4 = x + 6} \div \frac{2x}{1} \ = \frac{3}{x - 4 = x + 6} . \frac{1}{2x} \ \\ = \frac{3}{2 {x}^{2} - 8x = 2 {x}^{2} + 12x } = \frac{3}{0 = 20x} \\ \frac{3}{x = 0}$
