Solve for \( a \).

\(-2a - 9 = 6a + 15\)

Ok ready here we go
-2a-9=6a+15 +2a. +2a
-9=8a+15 -15. -15 -24=8a -24/8=a
Good luck

To solve the equation − 2 a − 9 = 6 a + 15 , first add 9 to both sides, giving − 2 a = 6 a + 24 . Next, subtract 6 a from both sides to get − 8 a = 24 , then divide by − 8 to find that a = − 3 .
