Answer:
a = 2.5
Step-by-step explanation:
a - 6 = 8 - ( 9 + a )
a - 6 = 8 - 9 - a
a - 6 = -1 - a
a = 5 - a
2a = 5
a = 2.5
Hope this helps and have a great day :)

Answer:
[tex]\boxed {a = \frac{5}{2}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]a[/tex]:
[tex]a - 6 = 8 - (9 + a)[/tex]
-To find the opposite of [tex]9 + a[/tex], find the opposite of each term:
[tex]a - 6 = 8 - (9 + a)[/tex]
[tex]a - 6 = 8 - 9 - a[/tex]
-Combine like terms:
[tex]a - 6 = 8 - 9 - a[/tex]
[tex]a - 6 = -1 - a[/tex]
-Add [tex]a[/tex] both sides:
[tex]a - 6 + a = -1 - a + a[/tex]
[tex]2a - 6 = -1[/tex]
-Add [tex]6[/tex] to both sides:
[tex]2a - 6 + 6 = -1 + 6[/tex]
[tex]2a = 5[/tex]
-Divide both sides by [tex]2[/tex]:
[tex]\frac{2a}{2} = \frac{5}{2}[/tex]
[tex]\boxed {a = \frac{5}{2}}[/tex]
Therefore, the value of [tex]a[/tex] is [tex]\frac{5}{2}[/tex].
