2-\left(-3a\right)-\left(-8\right)=1
To find the opposite of -3a-8, find the opposite of each term.
2+3a-\left(-8\right)=1
The opposite of -3a is 3a.
2+3a+8=1
The opposite of -8 is 8.
10+3a=1
Add 2 and 8 to get 10.
3a=1-10
Subtract 10 from both sides.
3a=-9
Subtract 10 from 1 to get -9.
a=\frac{-9}{3}
Divide both sides by 3.
a=-3
Divide -9 by 3 to get -3.
