ok so first you find like terms , so that's 3a - 2a
which equals 1a, which you simplify to "a".
Then what's left is +7 +4 which means 7+4
And that equals 11
So you put the 2 answers together to end up with the final answer:
a + 11 or 11 + a
..But then... you're supposed to put letters before numbers, so that means it cant be 11 + a. so the answer is : a + 11
Hope this helps and isnt too confusing. good luck !

Group like terms (put them near each other:
3a + 7-2a + 4 =0
3a -2a + 7 + 4 =0
3a and 2a are like bases, so you can subtract them like this:
(3-2)a + 11=0
a + 11 =0
subtract 11 from both sides
a = -11
is ur answer.
