5.

[tex]3(2x + 5) = - 9 \\ 6x + 15 = - 9 \\ 6x = - 9 - 15 \\ 6x = - 24 \\ x = \frac{ - 24}{6} \\ x = - 4[/tex]

6.

[tex] \frac{3}{4} (x - 7) = - \frac{1}{4} (2x + 5) \\ \frac{3}{4} x - 5.25 = - 0.5 + 5 \\ \frac{3}{4} x = 4.5 + 5.25 \\ \frac{3}{4} x = 9.75 \\ 3x = 9.75 \times 4 \\ 3x = 39 \\ x = \frac{39}{3} \\ x = 13[/tex]
