okay so first you distribute the negative to (2+3) so you get a-2-3=-2 then you move -2 to other side so you do +2 & -a so you get -3=-a then you divide both sides by -1 (there is always a 1 in front of variables) so then you get 3=a
answer:
a=3
hope this helps and i was clear. also your work could be simplified further by just adding the negative 5 to the negative 2.
5+-2 = 3 and a is isolated so again,
a=3
:) thats your answer
if its right plz give me brainliest
