-4 + 10 + 6a - 2a + 3 9 + 4a
5a-20+2a = 6a-11 5a+2a-6a = 20-11 1a = 9 a = 9
6a to the second power minus 8ab + 2a
The value of a in the equation 5a plus 2a = 6-6a is a=6/11.
2a² + 6a
6a squared-8ab+2a factor completely and check mentally
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
