It seems like the question is incomplete, but assuming you meant to ask "What does 6a plus a equal?" In that case, the answer would be 7a, as you are combining like terms by adding the coefficients of the variables. The expression simplifies to 7a because 6a + a = 7a.
6a plus 18b = 24
6a
Divide by 6a: 6a(a + 3b)
6ax2 + 6ax + 6a = 6a(x2 + x + 1)
98a + 5 + 6a = 104a + 5
18
-6a + 8 = 2 -6a = -6 a = 1
12a2b + 6a = 6a(2ab + 1)
-4 + 10 + 6a - 2a + 3 9 + 4a
the answer is 6a
6(a+b)
