Encontre o valor de x:

Answer 1

D)

$\frac{2}{4} + 4x - 9 = \frac{3}{2} - 4x \\ 4x + 4x = \frac{3}{2} + 9 - \frac{1}{2} \\ 8x = 1 + 9 \\ 8x = 10 \\ x = \frac{10}{8} \\ \boxed{x = \frac{5}{4}}$

E)

$5x - 10x = - 2(2x + \frac{12}{2} x) + 20 \\ - 5x = - 2 \times (2x + 6x) + 20 \\ - 5x = - 2 \times 8x + 20 \\ - 5x = - 16x + 20 \\ 16x - 5x = 20 \\ 11x = 20 \\ \boxed{x = \frac{20}{11}}$
