Answer:

Step-by-step explanation:

2)  

x + 14 \frac{13}{25}  =  -0.87

x + \frac{363}{25} = - \frac{87}{100}

x + \frac{1452}{100} = - \frac{87}{100}

x  = - \frac{87}{100} - \frac{1452}{100}

x = - \frac{1539}{100}

3)

x -8 \frac{5}{6} = 1.5

x - \frac{53}{6} = \frac{9}{6}

x =  \frac{9}{6} + \frac{53}{6}

x = \frac{62}{6}

x = \frac{31}{3}

4)

x - \frac{7}{12} = - 7 \frac{7}{16}

x - \frac{28}{48} = - \frac{119}{16}

x = - \frac{357}{48} + \frac{28}{48}

x = - \frac{329}{48}

5)

\frac{8}{9} - x = 6 \frac{1}{15}

\frac{8}{9}  = \frac{91}{15} + x

\frac{40}{45} - \frac{273}{45} = x

- \frac{233}{45} = x

x = - \frac{233}{45}

6)

-33.754 - x = 28.05

-33.754  - 28.05 = x

- 61.804 = x

x = - 61.804
