4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
10a + 3a - 4a = 9a
6-3a**2+7+4a-5a+18 3a**2-1a+31
4a-2=7a-6 4=3a a=4/3
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
It is 4a2.
If you mean: 4a +29 -3a -a +3a then it simplifies to 29 +3a
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
4a + 3a = (4 + 3)a = 7a
Add them together: 3a+4a-a = 6a
10a + 3a - 4a = 9a
(a + 2)(3a - 2)
6-3a**2+7+4a-5a+18 3a**2-1a+31
"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
4a-2=7a-6 4=3a a=4/3
10a − 3 − 4a
