a = 1/2
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
To simplify the expression (6a + 3b - 5a - 8b), combine like terms. For the (a) terms: (6a - 5a = 1a) or just (a). For the (b) terms: (3b - 8b = -5b). Thus, the simplified expression is (a - 5b).
6a
98a + 5 + 6a = 104a + 5
-6a + 8 = 2 -6a = -6 a = 1
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

6a
12a2/(2ab) = 6a/b
Divide by 6a: 6a(a + 3b)
54qba
It is 6a + 12, an expression which cannot be evaluated without the value of a.
