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}
