Answer:

Answer: a is -2

Step-by-step explanation:

[tex] - (5a + 6) = 2(3a + 8)[/tex]

open the brackets [ distribution ] :

[tex] - 5a - 6 = 6a + 16[/tex]

group like terms together:

[tex] - 5a - 6a = 16 + 6 \\ - 11a = 22[/tex]

divide both sides by -11 :

[tex] \frac{ - 11a}{ - 11} = \frac{22}{ - 11} \\ \\ a = - 2[/tex]
