Question

RESOLVER LAS ECUACIONES EN NUEROS RACIONALES.
x+3/5= -7/25
x+2/7=7/5
5 x=4/2+7/5 x
x+8/3=-2/5
6 x=3/2+5/4 x
2 x=1/2+9/3 x

Answer 1

Explicación paso a paso:

$x + \frac{3}{5} = - \frac{7}{2} \\ x = - \frac{7}{25} - \frac{3}{5} \\ x = - \frac{22}{25} \\ \\ \\ x + \frac{2}{7} = \frac{7}{5} \\ x = \frac{7}{5} - \frac{2}{7} \\ x = \frac{39}{35} \\ \\ \\ 5x = \frac{4}{2} + \frac{7}{5} x \\ 5x = 2 + \frac{7}{5} x \\ 25x = 10 + 7x \\ 25x - 7x = 10 \\ 18x = 10 \\ x = \frac{5}{9} \\ \\ \\ x + \frac{8}{3} = - \frac{2}{5} \\ x = - \frac{2}{5} - \frac{8}{3} \\ x = - \frac{46}{15} \\ \\ \\ 6x = \frac{3}{2} + \frac{5}{4} x \\ 24x = 6 + 5x \\ 25x - 5x = 6 \\ 19x = 6 \\ x = \frac{6}{19} \\ \\ \\ 2x = \frac{1}{2} + \frac{9}{3} x \\ 2x = \frac{1}{2} + 3x \\ 4x = 1 + 6x \\ 4x - 6x = 1 \\ - 2x = 1 \\ x = - \frac{1}{2}$
