2a-6a+9-4a+9
-4 + 10 + 6a - 2a + 3 9 + 4a
The value of a in the equation 5a plus 2a = 6-6a is a=6/11.
6a to the second power minus 8ab + 2a
2a + 5a + 3a = 10a
=6a
22
5a-20+2a = 6a-11 5a+2a-6a = 20-11 1a = 9 a = 9
2a² + 6a
6a squared-8ab+2a factor completely and check mentally
10a + 15 = 5 (2a + 3)
11a+7b-(3b-2a)
