Question

Me ayudan por favor
1)
$- 0.1x + \frac{4}{9} = - \frac{1}{18}$
2)
$\frac{2}{3} x - \frac{1}{2} = x + \frac{3}{4}$
3)
$\frac{4}{5} x + \frac{3}{4} = \frac{1}{2} x - \frac{1}{3}$
ES URGUENTE!!!!!!

Answer 1

Explicación paso a paso:

1)

$- \frac{1}{10} x + \frac{4}{9} = - \frac{1}{18} \\ - \frac{1}{10} x = - \frac{1}{18} - \frac{4}{9} \\ - \frac{1}{10} x = \frac{ - 1 - 8}{18} \\ - \frac{1}{10} x = - \frac{9}{18} \\ x = \frac{1}{2} \times 10 \\ x = 5$

2)

$\frac{2}{3} x - x = \frac{3}{4} + \frac{1}{2} \\ - \frac{1}{3} x = \frac{3 + 2}{4} \\ x = ( - 3)( \frac{5}{4} ) \\ x = - \frac{15}{4}$

3)

$\frac{4}{5} x - \frac{1}{2} x = - \frac{1}{3} - \frac{3}{4} \\ \frac{8x - 5x}{10} = \frac{ - 4 - 9}{12} \\ 12(3x) = 10( - 13) \\ 6(3x) = 5( - 13) \\ 18x = - 65 \\ x = - \frac{65}{18}$
