Well Dear Gladdo;
-2a+3+3a=9-24
It is our function;
◊ -2a+3a = 9 - 24 - 3
◊ [ -2 +3] a = 9 - 27
◊ 1a = -18
◊ a = -18
Good Luck Darling.

1. Rearrange so that the a's are on one side of the equals sign and the normal numbers are on the other side. I assume you know that when you switch sides you also switch plus and minus:
-2a+3+3a= 9-24
becomes
-2a+3a= 9-24-3
2. Add like terms. For "a" we have -2+3, which is 1. For numbers we have 9-24-3, which is -18, thus:
1a= -18
3. Divide by the number in front of the "a". Since we already have 1a (or simply "a") we don't need to do this step.
Thus, a= -18

Group the terms with a and the terms without a:
3a - 2a + 3 = 9 - 24
............- 3 = ..........-3 (subtract 3 from both sides)
3a - 2a = 9 - 24 - 3

-2a + 3 +3a = 9 - 24
add the 3a to the -2a
1a + 3 = 9 - 24
subtract 3 from both sides
a + 3 - 3 = 9 - 24 - 3
a = -18
ps '1a' is the same as 'a'

-2a+3+3a=9-24 combine like terms
-2a+3a+3=9-24
a+3=-15 subtract 3 from each side
a=-15-3=-18

The key thing is to SIMPLIFY each side of the equation first!
(-2a + 3a) + 3 = -15
a + 3 = -15
Then you need to get the variable by itself!
a + 3 - 3 = -15 - 3 ---> subtract 3 on both sides of the equation
a = -18

-2a + 3 + 3a = 9-24
(add As together)
3 + a = -15
-3...........-3 (minus 3 from both sides)
a = -18
