21a - 6a
To simplify the expression -5a - (-4a) - 3b, first, we change the double negative to addition, resulting in -5a + 4a - 3b. Next, combine the like terms -5a and 4a, which gives us -1a or -a. Therefore, the simplified expression is -a - 3b.
The expression "4a - 3 5a" seems to have a formatting issue. If it is meant to be "4a - 3 + 5a," you can combine like terms to simplify it to "9a - 3." If that's not the intended interpretation, please clarify the expression for a more accurate answer.
4a^2 - 5a^2 = -a^2
14a - 4a + 5a - 3a = 12a
5a - 10 = 4a + 8 is a linear equation in one variable.
4a - 5a^2
It is the same as: 9a -4a = 5a
A, 2A, 3A, 4A, 5A, and so on.
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
6-3a**2+7+4a-5a+18 3a**2-1a+31
5a or 4a squared
The GCF is 4a. The equation factors into 4a(5a + 9)
