10a + 3a - 4a = 9a
If you mean: 4a +29 -3a -a +3a then it simplifies to 29 +3a
The GCF is 2a.
4a + 3a = (4 + 3)a = 7a
Add them together: 3a+4a-a = 6a
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
The greatest common factor (GCF) of 4a and 10a is 2a. To find the GCF, we need to identify the largest factor that both 4a and 10a have in common. In this case, both 4a and 10a can be divided by 2 and a, making 2a the greatest common factor.
"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
If all the variables are the same, you just add (algebraically add) the numbers. For example: 3a + 4a = 7a 2a - 10a = -8a
12a + a - 3a = 10a
2a
-7a + 3a = -4a
