Answer 1

Explicación paso a paso:

$a. \frac{3}{4} x = \frac{5}{8}$

$3x = \frac{5}{8} \times 4$

$3x = \frac{5}{2}$

$x = \frac{ \frac{5}{2} }{3}$

$x = \frac{5}{6}$

B.

$\frac{2}{5} x = \frac{3}{7}$

$2x = \frac{3}{7} \times 5$

$2x = \frac{15}{7}$

$x = \frac{15}{2 \times 7}$

$x = \frac{15}{14}$

C.

$- \frac{3}{7} x = \frac{5}{4}$

$- 3x = \frac{5}{4} \times 7$

$- 3x = \frac{35}{4}$

$x = \frac{35}{ - 3 \times 4}$

$x = - \frac{35}{12}$

D.

$4x = \frac{2}{3}$

$x = \frac{2}{3 \times 4}$

$x = \frac{2}{12}$

$x = \frac{1}{6}$

$- \frac{1}{3} x = 5$

$x = 5 \times - 3$

$x = - 15$

E.

$- \frac{3}{11} x = \frac{5}{22}$

$- 3x = \frac{5}{22} \times 11$

$- 3x = \frac{5}{2}$

$x = \frac{5}{ - 3 \times 2}$

$x = - \frac{5}{6}$
