3a + 4a +/- 6; take the 3a & 4a and combine them; 7a +/- 6 would be your answer as 6 cannot combine with 7a due to the variable. If 7a +/- 6 = 0, then subtract/add (respectively) the 6 depending on the operation. Therefore 7a + 6 = 0 turns to 7a = -6. Divide the 7 with the -6 to get the a alone; a = -6/7 or -0.8. Cannot be simplified.

12 - 10 + 4 = 6
9 + 9 + 9 + 9 + 9 + 9 + 6 + 6 + 6 + 6 + 2 + 2 + 23 + 3 + 3 + 4 + 4 + 4 = 123
2 + 3 + 4 + 5 + 6 = 20
I assume that you mean n = 3 6n + 4 = 6(3) + 4 = 18 + 4 = 22

12 - 10 + 4 = 6
3+4+6+4=17
3 + 6 + 4 = 13
-6 + (-3) + 4 = -5
6 + 4 + 3 + 4 + 4 + 5 + 4 + 6 + 5 + 4 + 8 + 4 = 57
4 plus 6 plus 3 equals?Add 4 and 6 and get 10, then add 3 and 10 and get 13. Therefore, the answer to 4+6+3 is 13.
-6=-6(-a+2)+3(a-4)
9 + 9 + 9 + 9 + 9 + 9 + 6 + 6 + 6 + 6 + 2 + 2 + 23 + 3 + 3 + 4 + 4 + 4 = 123
8 + 8 + 6 + 3 + 4 + 3 = 32
