12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
a+6a+a=8a
6a plus 18b = 24
6a
98a + 5 + 6a = 104a + 5
2a² + 6a
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
11a+7b-(3b-2a)
21a - 6a
(a^2+7a-8)/(a^2+6a-7) (original equation) (a+8)(a-1)/(a+7)(a-1) (simplify top and bottom) (a+8)/(a+7) <--answer
a+6a+a=8a
6a^2 - 6ab + 7a^2 = 13a^2 - 6ab = a * (13a - 6b)
6a plus 18b = 24
6
12a2/(2ab) = 6a/b
6a
