Question

Resolver los siguientes ejercicios.

Answer 1

Respuesta:

$2 - x = \times - 8 \\ - x - x = - 8 - 2 \\ - 2x = - 10 \\ x = \frac{ - 10}{ - 2} \\ x = 5$

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

$1 - \frac{x}{3} = \frac{5x}{3} \\ 3(1 - \frac{x}{3} ) = 3( \frac{5x}{3} ) \\ 3 - x = 5x \\ 3 = 5x + x \\ 3 = 6x \\ \frac{3}{6} = x \\ \frac{1}{2} = x$

$\frac{2x}{3} + \frac{16}{3} = - \frac{4x}{2} \\ 6( \frac{2x}{3} + \frac{16}{3} ) = 6( - \frac{4x}{2} ) \\ 2 \times 2x + 2 \times 16 = 3 \times ( - 4x) \\ 4x + 32 = - 12x \\32 = - 12x - 4x \\ 32 = - 16x \\ \frac{32}{ - 16} = x \\ - 2 = x$

$\frac{1}{2} ( \frac{4x}{3} - 4) - 4 = 0 \\ ( \frac{4x}{6} - 2) - 4 = 0 \\ 6[( \frac{4x}{6} - 2 ) - 4] = 6 \times 0 \\ 4x - 12 - 24 = 0 \\ 4x - 36 = 0 \\ 4x = 36 \\ x = \frac{36}{1} \\ x =9$
