3a * * * * * Actually, it is 4a.
2a + 3a + 4 = 5a + 4
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
3a plus 4 equals 3a +4. You can not combine the two parts because they are not like terms so there is no way to simplify this.
2a + 4b
3a + 5b - 6a - 9b = -3a - 4b
You would factor 3a + 9b as: 3(a+3b)
3a * * * * * Actually, it is 4a.
When simplified it is: 2a+8b+4
2a² + 6a
-7a-7b
2a + 3a + 4 = 5a + 4
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
5a + 11
2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
3a plus 4 equals 3a +4. You can not combine the two parts because they are not like terms so there is no way to simplify this.
2a + 4b
