-7a + 3a = -4a
14a - 4a + 5a - 3a = 12a
3a * * * * * Actually, it is 4a.
3a - 2b
If you mean: 4a +29 -3a -a +3a then it simplifies to 29 +3a
10a + 3a - 4a = 9a
"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
-7a + 3a = -4a
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
14a - 4a + 5a - 3a = 12a
3a * * * * * Actually, it is 4a.
3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.
6-3a**2+7+4a-5a+18 3a**2-1a+31
If your problem looks like this: 4a-a=_ the answer is... 3a
5x - 8a + 4a - 2x + a = 3x - 3a
3a - 2b
(a + 2)(3a - 2)
